a whistleblower with the faa says his department failed to address a serious safety problem. tonight at 6:30, an nbc bay area investigative unit report. federal investigators reveal new information about that serious danger chevron employees were in during monday's refinery fire. i'm rob mayeda tracking a bay area heat wave. day four that brought temperatures up to 105 degrees today in parts of the bay area. we'll let you know if it's going to stick around to wrap up the weekend. your forecast is coming up. good evening. i'm diane dwyer. the weather was classically bay area today, very, very warm, perhaps even hot inland and a

bit chilly on the coast. here's a live look from our sunol camera where today's high, 104 degrees. compare that to half moon bay which was in the low 60s. meteorologist rob mayeda has been tracking the weather for us. >> you said it. uniquely bay area. we're getting a great tour of our bay area microclimate where you can just get in a car, drive half an hour and you can find relief around the bay area but you have to get close to the water to find it. half moon bay, 62 degrees. almost 40 degrees warmer towards fairfield and livermore. thathcgrridor east of 680 and the east bay and areas south of san jose saw temperatures climbing close to 100 degrees. bone dry conditions in the east bay hilltops. the only reason we don't have a red flag warning is the winds aren't sustained and strong enough to keep things for fire danger extraordinarily high with the low humidities and hot temperatures. the cooling we have, right now, only on the coast. we need that marine layer to thicken up and come rising over the coastal hilltops before we see a break in the heat inland.

fortunately your sunday forecast doesn't look like that's in the cards for us. and watching big thunder toward the syria serras -- sierras. today's hot temperatures didn't stop hundreds of people from visiting downtown san jose for the second day of the annual san jose jazz festival. >> the heat is not affecting my day at all. i have a great hat. and i have a very light clothing on. and there's a fabulous breeze. so if you just hold your arms up a little bit, totally cools you off. >> great hat indeed. the san jose jazz festival continues through tomorrow. we have new information tonight about that refinery fire in richmond. federal investigators say dozens of chevron workers were nearly killed when that leaky pipe burst. a team with the u.s. chemical safety board of investigators says that seconds after the pipe burst, employees nearby were

caught in a highly flammable vapor cloud. if the employees had not evacuated as quickly as they did, many of them could have been killed or severely injured. investigators also say they have questions surrounding a shutdown of that very same refinery unit last year. >> back in november 2011, there was a maintenance shutdown in that refinery unit. and a pipe adjacent to this pipe was actually found to be bloated and was replaced. the pipe that leaked was not replaced at that time. understanding that decision is going to be one of the important focuses going forward. >> investigators say while no one was killed, monday's fire is one of the most serious refinery incidents in u.s. history. five refinery employees were hurt and hundreds of people who lived nearby were treated in local hospitals. tonight, an nbc bay area investigative unit report that looks into a possible safety

defect that could jeopardize both emergency rescue workers and the people they're trying to save. our investigative team discovered that a lack of action by federal regulators could be putting lives at risk. investigative reporter stephen stock has more. >> reporter: talking about night vision goggles, tools to make rescue flights safer. but one faa safety inspector says there is a problem with them, a problem he called attention to years ago, a problem he says still has not been completely fixed. according to the faa, hundreds of helicopters are now using night vision goggles, the types of helicopters range from calstar to california's highway patrol. all of them faa inspector ran

foster says they could impair the pilot's vision and ability to fly safely while wearing the goggles. >> it's extremely serious. you have helicopters operating in an emergency condition in an unknown area. the public expect that is we did our job right. in this case, we didn't. >> reporter: when foster talks about we, he means the agency he still works for, the faa. foster first notified the faa about this problem back in 2008 and then again in 2010. the faa was even called to task by the office of the special council after its own independent investigation into this issue which resulted in this may letter to the president of the united states. >> the problem is the wrong color of filter, the wrong lights are on there, they interfere with the vision. so you can't see. >> reporter: the faa told us, quote, safety is the faa's top priority and it says they've now taken action to fix this problem. but critics say that action is

too little too late. coming up later tonight, we'll take you on board these helicopters and show you firsthand exactly what can happen and we will talk to pilots about the dangers after what amounts to flying blind. that's later tonight after the olympics right here on nbc bay area news. >> if you have a tip for our investigative unit, give us a call at 888-996-tips. or you can send us an e-mail. now to our coverage of the 2012 london olympics. we're in the home stretch of the games. the closing ceremony is tomorrow night. but it is not over yet. in fact, saturdays are traditionally some of the busiest days of the games. and today, 32 gold medals were up for grabs. phil rogers joins us from london with word that the olympics might be headed back to the u.s. as well. hi, phil. >> reporter: hi, diane. you are absolutely right. in fact, today was the busiest day yet for the olympic games.

and now london is sprinting to the finish. in olympics-crazy london, the party is almost over. and the british are already feeling the pain. >> feel gutted, really. we've really loved watching all of the games, every single discipline, we've been on it. it's been fantastic. >> reporter: london's organizers have received high marks all around for spectacular games. and today, leaders of the u.s. olympic committee said it's time to bid on bringing that experience back to the united states as early as 2024. >> we think the games need to come back to america. and the sooner, the better. >> reporter: with america leading the gold medal counts, they say they are happy with the team's record, especially with the women. the sole exception, usa men's boxing which was sank singled out today as a stunning disappointment. no medals for the first time in olympic history.

>> we have to fix that. we have to change that. >> reporter: there's little to fix with team usa and men's basketball. heavy favorites to win the gold medal against spain. >> if we win, people say we weren't supposed to win. >> reporter: brazil was a heavy favorite to win the only major soccer championship that's been denied. but mexico spoiled the party today. peralta scored twice allowing mexico to celebrate its first soccer gold. $155 will buy you an entire bedroom set from the athletes village. a website called remainsofthegames is selling everything that's not nailed down in the olympic park. for $29, you can buy an individual nightstand. and it might just be the very nightstand where michael phelps would flop his medals every night before switching out the

lights. >> thank you, phil. we covered beijing together and my personal highlight was the food was so interesting and spectacular there. what's your highlight so far of the london games? personal or professional. >> reporter: oh, diane, absolutely the way they have melded british culture with these games. this is such a historic city. and they have put the venues out in the most spectacular places. you have rowing out at windsor castle. and you have different events taking place at hampton court where henry viii used to live. they have blended this city with the olympics in such a spectacular fashion, it was a pleasure to be here. >> thanks a lot, phil. there was a shocker at the olympics day on the soccer field and we found many bay area soccer fans who just loved every minute of it. fans at this restaurant in san francisco celebrated as mexico

stunned brazil 2-1. and it's the first medal of any kind in soccer for mexico. >> really nice. can want believe it. first time, awesome. we are so excited. it's in our hearts. >> brazil was heavily favored to win that game. and we are more of our exclusive olympics coverage coming up, including the bay area rivalry that's alive and well across the pond. it's cal versus stanford. athletes from both schools have been collecting the medals. but who's in the lead, you ask? we'll show you. also -- >> he's done something that very few people in washington learned how to do. >> that's mitt romney talking about his running mate. our political analyst will join us to tell us why romney chose paul ryan. >> reporter: i'm kimberly terry

live in san jose. i'll tell you people's reaction to romney's pick for vp in a live report coming up.

feels good to be here in the center of the universe. >> mitt romney chooses his running mate, wisconsin congressman paul ryan. the choice is considered risky by many experts. in a moment, we'll talk with our

political analyst. but first we want to go to kimberly tere in san jose with a look at some local reaction to that choice. hello, kimberly. >> reporter: hello, diane. those opinions about mitt romney's choice for vice president were varied but went along party lines. the one thing we did keep hearing is that romney's campaign needs an energy boost. but is paul ryan the person to do that? >> i think it's a great pick for the democrats. couldn't be better. terrific. he's going to make a great target. >> the smartest republicans realize they can't win this year. if they thought they had a chance, romney would not be the candidate. and ryan is collected as the heir apparent in 2016. i look forward to his ideas of trashing the new deal and medicare as the way for the democrats to win in 2016 as they will this november. >> i think it will give them a little bit more popularity with people he's not so popular with now. i think he will get more of the

tea party vote and things like that. so i think for him, it was a good choice. >> i think congressman ryan with his budget experience and being in congress and knowing our federal budget inside and out helps balance the ticket out and will be able to advise governor romney as well as help tackle these issues once romney is elected. >> reporter: very different response there is as to romney's vp pick. it appears from the people we heard from today that this is an election they are paying close attention to and will continue to do so through november. live in san jose, kimberly tere, nbc bay area news. >> kimberly, thank you. president obama met with his campaign team in chicago this afternoon, a few hours after his rival named his running mate. his campaign is reacting to the announcement by leveling some harsh criticism against paul ryan on twitter at least. staff tweet that had ryan, quote, is an architecture of the topdown gop budget that cuts education, energy and innovation even as it gives tax cut to the

wealthy, unquote. that comment was followed by a series of facts about ryan including that he would ban all abortions, even in cases of rape or incest and that he co-sponsored a bill that would ban many common forms of birth control. right now, we want to bring in nbc bay area political analyst larry gerston. thanks for joining us. why paul ryan? many americans have never even heard of him. >> ryan most closely meets romney's needs. he's young and dynamic, a favorite of the tea party. he's steadfast in his desire to keep taxes low and shrink that federal government, particularly in terms of social security and social welfare program. he matches up on the social issues such as abortion. we know this. immigration, marriage is defined as a relationship between a man and a woman. it's a pretty good fit in a lot of ways.

his conservatism is going to help romney motivate the base he needs to get excited. >> there are problems for romney and the conservatives to be concerned about, right? >> oh, yeah. we saw the democrats. they think they have ryan where they want him and romney as well. they see ryan as a reckless addition and a target. they're going to pummel ryan when it comes to things such as cutting social security. democrats believe they will criticize the budget proposal as favoring the rich and harming the middle class, leaving them behind. and they're going to go after romney and ryan as being anti-women when it comes to those birth control questions and the abortion questions. most of all, the democrats believe that while romney and ryan may win votes from that base, that critical base it is, they'll lose even more from moderate. >> that's why they're partially celebrating. how does this all play out for us in california?

>> for some people, there's golden in our states. and that means here. better than some might think. there's really no way that the addition of ryan to the republican ticket is going to turn california into republican red instead of democratic blue. we can put that out right away. the voter id percentages here don't come close. but here's where romney scores and he scores big with money people. so far he's already raised $35 million to $40 million in california, in blue california alone. wealthy conservatives are champing at the bit. they're more comfortable than ever contributing to the campaign with ryan on the ticket. and that money is going to be channeled to the swing state licke lickety-spl lickety-split. and before you know it, they'll have all kinds of dough to help here in california. >> thanks a lot, larry. well, it has been another hot day in the bay area. how long is this heat going to last? we're going to check in with rob mayeda who's been monitoring the situation for us. rob, what's happening.

>> right now, you just saw san ramon there. that's a pretty good spot there. 90 earlier. right now dropping into the 70s. look at fairfield and livermore. south of san jose, the numbers at the airport, 89 degrees. south san jose, 98, 99, los gatos. morgan hill, 101. if the sea breeze not particularly strong tonight, you can see we're still sitting in the upper 90s inland. out towards fairfield and livermore, slow to no cooling inland even though the wind is coming in from the right direction. it's like the fan is on but the coolant isn't in the ac just yet. the marine layer is going to thicken up. for sunday, slight cooling. but if you compare 97 degrees to 105 degrees, they both feel pretty hot. to see upper 80s and low 90s, that's going to take some time. we'll get the cooling next week. at the coast, continued cool

with a lot of misty skies. we get the mist and fog on the coast from the golden gate down to santa cruz. the trip over highway 17, if you have the patience, you'll find 70 around santa cruz tomorrow. monsoon moisture triggering thunderstorms there. look out in the high country the next few days. high pressure holding its ground for now, today was the hottest day of this heat spell. going to be hot inland. maybe near 100 in the same locations tomorrow. slightly cooler inland. more significant cooling around the inner bay and coast. as that marine layer starts to thicken up by tomorrow at this time heading into monday, we'll see the temperatures drop off. >> good news for sunshine on the coast tomorrow. should get brief to midday clearing. tonight, speaking of low clouds, the fog and mist on the coast. but this is a problem tonight because we want the clear skies.

we have the perseid meteor shower that's coming. that's coming up after midnight tonight. mid to upper 80s around san jose. mid to upper 90s inland, south of downtown san jose. trivalley, pretty toasty. going to take a few more days for those cities to cool off. 60s in san francisco and the coast. heading towards the middle part of the week, watch the top bar. inland valleys, looking at a couple of degrees of cooling each day. this is a slow ramp-up of the ocean air conditioning. once the marine layer gets closer to 2,000 -- it's about 1,000 right now -- that's when it's going to punch over the hilltops. if you're around the inner east bay, the hilltop, it's been comfortable this weekend. but very toasty inland. >> thanks a lot, rob. still ahead, do these

billboards go too far? they're up in one bay area city and they tell a certain group of people they deserve to die. two bay area universities have more medals than a lot of countries. we're looking for the secret to their success.

as the olympics wind down, we're taking stock of the success of athletes from bay area universities and the rivalry between cal and stanford is alive and well. as of right now, it's a tie. former or current students from stanford have won 16 medals at the games. same for uc berkeley.

nbc bay area's arturo santiago is at cal right now where he spoke to the school's athletic director. hello, arturo. >> reporter: hi, diane. the success both schools is having is simply astounding. cal has 11 gold medals, one silver and four bronze. stanford has 12 gold medals, two silver and two bronze. cal, however, does have a chance to break the tie. now, the women's volleyball team was practicing inside today when we caught up with cal athletic director sandy barber. cal has 46 athletes and five current coaches participating in the 2012 summer olympic games. if cal was its own country, it would rank 15th among countries in the number of medals won. she says much of their success can be attributed to the athletic tradition at the school. but most importantly, she says there's a culture of excellence that exists throughout the entire campus. >> from the athletics perspective, we're trying to play our part, we're trying to

fit in with the rest of campus. it's about coaches and student athletes and support staff and administrator that is get up every morning thinking about how do we get better today? >> reporter: now, she also talked about the huge rivalry between stanford and cal, even when it comes to the medal count. but athletes from both schools have also been teammates. and there's a certain pride in finding success together. now, again, cal does have a chance to win -- has a couple of more chances to win a medal. if either of those men can medal in either event, cal would have the edge over stanford. arturo santiago, nbc bay area news. >> arturo, you know as journalists we're supposed to be unbiased. but this is a friendly rivalry, cal and stanford folks love each othe i'm rooting for the cal folks tomorrow. thanks a lot.

the u.s. men's basketball team is gearing up for tomorrow's gold medal match against spain. team usa is a heavy favorite. for the most part has easily handled this competition so far. but spain comes with size. the u.s. team has not seen that during the olympic games. >> very excited. i'm thrilled to have this opportunity again to defend our gold medal. looking forward to going out there and competing. it's going to be fun. >> the game is a rematch of the 2008 final in beijing from team usa came out on top. as for the women, they made it five straight gold medals today beating france by a final score of 86-50. the victory sends the team's win streak to 41 games. and the women's last olympic loss was at the barcelona games 20 years ago. the u.s. has only lost three times since women's basketball was added to the olympics back in 1976 and currently has seven gold medals. coming up, a controversial

debate over who deserves to die? new billboards in san francisco are doing some finger-pointing. we'll show you who they're targeting. and our own raj mathai takes us to one of the most famous spots watched in the world. here's a hint, it's in london and the fab four walked across it. the summer games are coming to a close but the olympic caldron is still burning and athletes are still going for gold. all the action you can catch tonight in primetime.

we want to take you back out to london where the stage is now set for the final events, believe it or not, of the olympic games. mark barger joins us with a preview of the big event airing in primetime tonight. hello. >> reporter: that's right, diane. it's kind of the cap for what's been a big day here at the games. 32 gold medals at stake today.

the busiest day of the games. and some of the big action tonight is going to be on the track, as usain bolt will be trying to make it a double tribtrib triple. he'll be competing in the 4 x 400 meter relay. you have to make a clean handoff. that adds of drama and unpredictability to the relay. the u.s. has had trouble with that in recent years. we'll see if they can give mr. bolt and company a run for their money. and tonight, the women's 800 meters. and cal alum alysia montano will be running in this one. this is her first olympics. her time right now is only about .16 out of third place. she had a very good chance of being in medal contention tonight. and we'll see women's indoor

volleyball, the u.s. women going for their first-ever gold medal against the brazil. the brazil will try to salvage national pride because their men's soccer team lost in a big upset today. brazil also looking to score a gold medal tonight. and we have 10 meter platform diving. these two guys teamed up to win a medal in synchronized platform diving. they are both medal contenders. >> mark, the closing ceremony is tomorrow. any idea what kind of show we can expect this time around? >> reporter: you can expect a lot of music. a symphony of british music is the way they're titling this. looking for 30 songs. the music director went after every big name act he could get. there were two that turned him down to take part. and those same two acts called him back after the opening ceremony, tried to get into the

closing ceremony. he said, too late. we're already filled up. we don't have room for you. that's an idea of how much musical talent you will see tomorrow night during the closing ceremony. >> that will teach those two. thanks a lot, mark barger reporting for us from london. our own raj mathai has been right in the heart of all the olympic action in london. but he's also had some time to do a little bit of sightseeing. he checked out a place that could be considered sacred ground for music fans. >> reporter: hello from london. coming to you from not big ben or the tower bridge, but it's the most famous crosswalk in the world. it's abbey road, the place the beatles made so famous, 43 years ago this week f you need a little refresher, here it is, john lennon, ringo starr, george harrison. the photographer got the shot

and the rest is music history. a lot of people come here every day, hundred ifs not thousands. and it's not just us but there's a live camera. we're going to wave to it. a live 24/7 web camera broadcast around the world. and there's a bit of beatles trivia for you. the last time they had a live concert was at candlestick park in august of 1966. sir paul maccartney was part of the opening ceremony. good chance we'll see him at the closing ceremony on sunday. george michael, adele, coldplay and the spice girls are also in the show. a world record for team usa, the women's 4 x 100 relay race and there's a bay area connection. this is jeneba.

she didn't race in the finals but she is part of the team so she does get a gold medal. congratulations to her. that's going to do it from here. saturday in london, we'll see you tomorrow during the closing ceremony. i'm raj mathai. back to you. >>here's a lot to celebrate as the 2012 london olympics come to a close. if you'd like to take a look back at some of the best moments, you can always go to nbcbayarea.com, scroll down to the london 2012 section and click on london 2012's most memorable moments. happening right now, firefighters near san diego are working to contain a wildfire that's burned more than 2 1/2 square miles so far. the fire is burning northwest of warner springs. today, we're told the fire is about 40% contained. the nearly 800 firefighters on the scene are hoping to gain full containment by the end of monday. and no homes are threatened at this point. we're learning the man accused of gunning down 12

people in that movie theater in colorado received many accolades in the academic world. the university of illinois released documents today related to james holmes. holmes applied and was offered a full scholarship to a graduate program at that school. there were several letters of recommendation. one described him as having, quote, a great amount of intellectual and emotional maturity. holmes turned down illinois to attend the university of colorado, his own personal statement on that application discussed, quote, the need to study the primary source of all things, our brains. and we have a controversial campaign that says hipsters, tattooed people and the genetically privileged, quote, deserve to die. the campaign is popping up in major cities across the united states including in san francisco. but backers of the campaign are urging people to read between the lines for a much deeper meaning.

nbc bay area's kimberly tere has that story. >> reporter: death wishes are being aimed at good-looking people, cat lovers and others, all in a bold attempt to bring attention to the stigma associated with lung cancer. some people think they deserve to get the disease. >> i thought, this is perfect. people should be outraged. nobody deserves to die. not cat lovers, not lung cancer patients, not smokers. some lung cancer patients have never smoked and we need to understand that. but my point is that even if they have smoked, they did not bring this on themselves. they don't deserve it. >> reporter: the lung cancer alliance which paid for the billboard is hoping to get people talking and seeking out more information about the disease. while it's no secret tobacco increases one's risk of getting lung cancer, the alliance is hoping to show that there are other risks as well.

>> lung cancer stigma gets in the way of communication with physicians. >> reporter: she says anyone can get the disease. >> we really need to look at our attitudes and be outraged when people say smokers deserve to die. >> reporter: the billboard at muni stops in san francisco and other major cities across the nation are causing mixed reactions and even some anger and confusion. >> it's a sad message. that scares me. >> doesn't mean rich, poor or whatever you are. we all deserve to live happy and appreciate every moment we are living on. >> reporter: this san francisco couple says it's an individual choice whether to smoke but bottom line, lung disease is not discriminating and compassion shouldn't be either. >> i know the most healthy people in their life, they get cancer. and of course they don't deserve to die. >> reporter: kimberly tere, nbc bay area news. it's a first. the national democratic party is

endorsing gay marriage as part of the platform for the first time. the platform committee met today in the work of a separate group that drafted the section two weeks ago. the document says democrats support marriage equality and the movement to secure equal treatment under the law for same-sex couples. the platform is a broad statement of the party's priorities and next goes to the national convention next month in north carolina. the hope is that support for gay marriage will attract young people to the democratic party. and still to come, the bay area fisherman that caught the unexpected. the fishing buddies behind this incredible video tell us how they got up close and personal with these gorgeous dolphins. when they're in pain and they're going through stuff that no child should ever have to go through, if you could bring a smile to that kid's face, why wouldn't you? >> a business is shelved and a cape-making crusader was born. a mother who uses what she learned from her autistic son to

it's one of the hardest jobs as a parent, taking care of a very sick child. while doctors try and cure, it's a parent's job to comfort. one east bay woman is helping parents all over the country do just that. it is a crusade she didn't choose but one she can never give up. nbc bay area's garvin thomas is here with tonight's bay area proud. >> i'm going to go ahead and sew it.

>> reporter: you'd figure anyone who spent as much time at a sewing table as barbara casados does hers would have an amazing repertoire with needle and thread. at the very least, after thousands of hours, they could cover the basics. >> i have to make sure it lines up. >> reporter: but ask this danville mother of three to sew a button on a shirt or hem a pair of pants, here's what she'll say -- >> no. i would if i could but i can't. so i won't. >> reporter: there is just one thing she knows how to sew, yet hundreds who are thankful for it. >> make superhero capes. that's it. show me your muscles! >> reporter: barbara's one-track sewing mission started in the family with the middle of her three sons, maddox. diagnosed with autism, he was having trouble dressing himself and fighting mom every step of the way if she tried to help. >> it became a daily battle that

i didn't want to deal with anymore. and my friend made a cape and i had said, if you let mommy dress you, you can wear your cape to school. huge. loved it. >> reporter: loved it so much and wanted so many more that barbara taught herself how to sew one. maddox's friends liked them, too. and soon barbara was making so many capes, it was becoming a business. that is, until a friend send barbara a list of sick children who might like a superhero cape. she thought she'd do a few. >> well, i got that list. and there were 67 children on that list. and i couldn't pick. >> reporter: she made capes for all of them. and when the pictures came back of sick kids with smiles, a business was shelved and a cape-making crusader born. >> it's that brief time that they can smile, when they're in pain and they're going through stuff that no child should ever have to go through, if you can bring a smile to that kid's face, why wouldn't you? we have the girl ones over here.

>> reporter: barbara has just in the past few years sewn more than 500 capes. many are shipped around the country. a lucky few, though, get them delivered in person. earlier this month, barbara handed out more than 60 capes to the children at stanford's ronald mcdonald house. the smiles she saw in those pictures are even brighter in person. >> they wear the cape and they feel bright. it gives them that sense of, it's going to be okay. it's like their blankie. but it's a cool blankie. >> that is a special lady. a santa cruz surprise, a pot of dolphins captured by a bay area fisherman on type. check out this video. 42-year-old mark peters in martinez took this footage on a cruise for tuna. he took out his video camera

that was rigged with a new flat lens and lowered it just about ten feet below the surface and these are the pictures he got. they slowed the boat to about 8 miles an hour and then let the dolphins swim right up to that camera. >> it's a very wide-angle lens. so you could tell in the video they're right up next to it, within inches of it. i think they're just curious, were checking it out. >> peters posted the video and it got more than 180,000 hits within a week. just beautiful. right now, we want to check in with mendy bach of comcast sports net. >> the a's on the south side of chicago in another close game with the white sox. the giants, thanks to buster posey found their offense. highlights are coming up next.

the giants have not been

hitting at home and they have not been winning at home. but somehow they were tied atop the n.l. west with the dodgers heading into today's game against the rockies. but they know that will not last if they don't turn this thing around. a beautiful day outside. food, not on the minds of the giants. buster posey leads the majors in average since the all-star break. he gets his 19th home run of the season. two-run shot gives the giants a 4-0 lead. this is what they needed. with matt cain on the mound, especially. he was solid once again. ramon hernandez can only watch it go by. and everyone enjoying the six strikeouts that cain provided for the day. the giants had 13 hits and win big, 9-3. here's more from at&t. >> reporter: after getting shut out the night before, the giants's offense exploded on saturday for nine runs including a home run by buster posey, just the 18th hit by a giant here at at&t park this season. >> the fellas needed that to put some runs on the board.

there's been so much talk about it. it's good to see them have some success, put some runs on the board there. hopefully we start getting some momentum going here. >> i think we definitely know what our offense is capable of and just came off of a good road trip. it was nice to get some runs across today. >> we're capable of rattling off quite a few runs. cain really set the tone, pitching well. that's where it starts, with pitching. all-around good ball game today. >> reporter: the giants will get another offensive boost soon as pablo sandoval is expected to return in time for the nationals series. he is currently completing his relab assignment with san jose. and they hope to have him back on monday. reporting from at&t park, jay stier. the a's in chicago.

they had a three-run lead in the bottom of the fifth. and then kevin youkilis hits the big bomb. that's a two-run shot. and the white sox pull within one. in the bottom of the sixth, one hit shy of the cycle. this game tied at 6. white sox go ahead in the seventh but the a's answer with two more in the top of the eighth. and right now, they lead 8-7 going into the bottom of the eighth. third round of the pga championship a gloomy day and a strange day for rori mcilroy. watch where the ball lands. what are the odds of this? in the tree. mcilroy would eventually find the ball and would believe it or not par the hole. tiger woods, not tied for the lead. his second shot on 7 from the rough. goes into the crowd. he is 3 over par through seven holes. play was suspended because of bad weather.

mcilroy and vijay singh are your leaders. you saw the 49ers' preseason win last night. smith went out with a hip bruise. we know smith will be fine. we hope so, for the regular season. >> absolutely. thanks a lot, mindi. the america's cup is coming to san francisco next year but those competing in it will be racing here much sooner. as lawrence scott shows us, the stars of the sport are scheduled to be in the bay area in just about ten days to get things started. >> reporter: the sport of sailing is enjoying something of a revolution and it's being televised, from the olympics to the kind of action we're expect to see in the america's cup. people are noticing the buzz. and this ceo has certainly taken note. >> we're seeing that people are finally learning that sailing

itself is a sport rather than a pastime. and it seemed to be a pastime for the rich. it was called yachting for a reason. but there's been a tremendous democratization of sailing up and down. >> reporter: when stephen barclay unveiled all the events, we talked to him about the differences between the sailing at the olympics and the competition centered around the america's cup. >> you can't compare it. olympics styling looks a little bit like what you'll probably see on the bay on a sunday, a few boats going around with white sails on a blue background. what san franciscans are doing now, they're on the water, riding close, so they can touch it, so they can hear it. our ambition is to enhance that experience by live commentary coming off the boat. >> reporter: while as far as the visuals go we are seeing some similarity. >> one of the things that has

happened both in the olympics and in the america's cup is that they both worked hard to make it television friendly. so everything that larry ellison has done for the america's cup has all been done to make it exciting and interesting. >> can't wait for that either. let's check in with rob mayeda and what's going on with the weather for this weekend. >> right now, the weather starting to cool off finally around the inner bay. sea breeze taking hold over san francisco and oakland. but still 94 degrees in livermore. down to 76 in san jose. 91 in fairfield. got that south push of air cooling off the north bay valleys. and eventually it's going to turn stronger. maybe not so much tomorrow. we'll see a similar day tomorrow except the air quality starting to improve in the east bay. enough of a breeze to stir up some of those ground level ozone concentrations. not exactly a good day for air quality just yet. we need a strong sea breeze to take the edge off the heat.

santa cruz climbed into the low 70s earlier. but at the marine layer close to 1,000 feet, it's just the bay and the coast benefiting from the cooling. off to the east, you have your monsoonal thundershowers there from lake tahoe down towards yosemite. that, too, we'll see on sunday. tomorrow morning, waking up to patchy fog across the inner bay. misty skies on the coast. that is a problem for overnight meteor shower viewing. during the day tomorrow, north wind should mix in drier air which should lead to more sunshine along the beaches for a low time. then the low clouds will sweep back in leading to a cooler monday forecast. tonight if the fog fills in around the bay, head to the hilltops because we have the perseid meteor showers, look off to the northeastern skies after midnight tonight and maybe you'll see a sand-grain-sized particle moving and just vaporizing in the atmosphere, if you don't have the fog outside tonight. around lunchtime, 90s around the tri-valley.

look at the temperatures, looks a lot like today. if you want to find cooling in the seven-day forecast, you have to be patient. it's going to take some time. this is a slow ramp-up of the sea breeze which will eventually by the time we get to the middle part of the week, that's when places like livermore will finally dip back into the 80s and low 90s. but the beautiful thing about living in the bay area, drive 15 minutes. kind of chilly on the coast with those 60s. >> that fog was stick around. thank you, rob. just ahead a little girl power going on. the ladies of team usa have earned more than their fair share of medals in london and it's inspiring young athletes here in the bay area as well. we'll show you coming up.

that women are doing non-traditional sports. every time a woman does something a little above and beyond societal expectations, that opens doors for all of us. and i think that's fantastic. >> reporter: these girls also recognize the emotional and physical strength it takes for female olympic athletes to succeed. >> they are so tough. some of these sports, it's a guy's sport, no, the girls are definitely owning it. >> reporter: it truly is the year of the woman at the olympics this summer, thanks to those willing to break molds and create new ones. and inspire all of us on the way. marianne favro, nbc bay area news. >> i like the girl power. coming up next on nbc bay area, we have rob mayeda hosting the olympic zone, a behind-the-scenes look at the london games. and we'll sit down with two of the biggest stars of team usa, men's basketball, kobe bryant and kevin durant. they tell us which olympians at the london games have inspired
