when he lost the first two sets to australian tanasi kokkinakis, at 35 it seemed another grand slam hopee looked beaten. but, of course, murray never is. it's ridiculous! and while he milked the crowd, kokkinakis lost his cool. after serving for the match, that was the third set gone as murray rolled back the years. it was gutsy, it was glorious, and it was 2—2. by now it was more of an endurance test than a match, murray's longest ever. but after five and three quarters hours and gone 4am in melbourne, it was all worth it. he's officially superhuman. the word epic doesn't come close. a victory to defy time, logic and belief. i don't know how i managed to get through it. i did start playing better as the match went on. and, yeah, i have a big heart. delight, then, for him and his watching mum judy. another extraordinary chapter in one of british sport's most extraordinary careers. two days to recover and he goes again. that was a second round match. the third round is under way with british number one, cameron norrie, hoping to avoid such a marathon, and has just won the first set agains
