Federer talks lucky match-point let cords

Roger Federer, who sliced a backhand return on match point against John Isner that dribbled over the net for a winner in his 6-4, 7-6 (5) win over the American in the Olympic quarterfinals, says it has happened to him before. "First thing that came to my mind, was a Miami final, against [Ivan] Ljubicic," he recalled. "I won 7-6, 7-6, 7-6. It was also in the tie breaker, maybe 8-7. He hit it hard to my backhand and I chipped it over, the match was over and the tournament was over. I also got extremely lucky on that one. I actually did text him to tell him the same thing happened again, I can't believe it."
