Federer stunned in Wimbledon QF; Nadal, Djokovic, Isner win

Roger Federer was a point away from a rather tidy, straight-set victory in the Wimbledon quarterfinals. One lousy point.

And then, slowly, over the next two-plus hours, all the way until the fifth set reached its 24th game, as the temperature dropped and the spectators' cries of "Let's go, Roger!" echoed through the shadows, everything came apart for the eight-time champion. Against an opponent who'd never beaten him nor made it this far at the All England Club.

In a stunning turnaround in an unfamiliar setting — No. 1 Court instead of Centre Court — the top-seeded 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 No. 8 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," said Federer, who last played at No. 1 Court in 2015. "I almost could have. I should have."

While his tournament is over, two of his long-time rivals at the top of tennis set up a semifinal showdown: Rafael Nadal and Novak Djokovic. Nadal, who's won two of his 17 Grand Slam titles at Wimbledon, edged 2009 U.S. Open champion Juan Martin del Potro 7-5, 6-7 (7), 4-6, 6-4, 6-4 in a wildly entertaining match that featured diving shots by both and lasted 4 hours, 48 minutes.

Djokovic, whose 12 major championships include three from the All England Club, got to his first Grand Slam semifinal since 2016 by beating No. 24 seed Kei Nishikori 6-3, 3-6, 6-2, 6-2.

In Friday's other men's match, Anderson will face No. 9 John Isner, the 33-year-old American who reached his first major semifinal in his 41st try by eliminating 2016 runner-up Milos Raonic 6-7 (5), 7-6 (7), 6-4, 6-3. Isner hit 25 aces, saved the only break point he faced, and has won all 95 of his service games in the tournament.
