John Isner is one of the few who can say he's beaten Roger Federer. Now he has to do it again and on an Olympic stage, no less.
Isner faces Federer on Thursday on Centre Court at Wimbledon, which has been Federer's stomping ground for the better part of a decade. The Swiss superstar has won a record-tying seven Wimbledon titles, so he feels right at home in the London Games.
To advance, Federer will have to handle the 6-foot-9 Isner's mammoth serve.
"We know he's got one of the best serves on tour, if not the best," Federer says. "That obviously makes it complicated getting into rallies, into rhythm. That's grasscourt tennis."
Isner is 1-3 in his career against Federer.
"He's the hottest guy on the tour, he's back to No. 1 in the world," Isner says. "I'm going to have to serve well."
