LONDON — In a stunning turnaround in an unfamiliar setting — No. 1 Court instead of Centre Court — the top-seeded Roger Federer blew a third-set match point and, eventually, all of his big lead in a 2-6, 6-7 (5), 7-5, 6-4, 13-11 loss to eighth-seeded Kevin Anderson on Wednesday in a 4-hour, 14-minute tussle.

“It was just one of those days where you hope to get by somehow,” Federer said. “I almost could have. I should have.”

American reaches 1st Grand Slam semifinal

John Isner is ready to be associated with something at Wimbledon other than winning a 70-68 fifth set in the longest match in tennis history.

He figures a championship would do the trick — and now he is only two victories away.

Isner, a 33-year-old American playing in his 41st major tournament, reached his first Grand Slam semifinal by beating Milos Raonic 6-7 (5), 7-6 (7), 6-4, 6-3 at the All England Club on Wednesday.
