PARIS (AP) - Stumbling on his way to the net, Roger Federer dropped his racket and fell to his knees on the red clay. Hardly the sort of grace and precision the world has come to expect from the 17-time Grand Slam champion.

There were other unusual sights in Federer's 6-4, 6-3, 7-6 (4) loss in the French Open quarterfinals against his pal and Swiss Davis Cup teammate Stan Wawrinka.
Rarely injured and appearing in a 62nd consecutive major, Federer received treatment on his right hand from a trainer. For years and years a dominant and confident force in tennis, Federer slumped in his changeover chair, head bowed, after falling behind two sets to none. And, according to the ATP, this was the first time since a fourth-round loss at the 2002 U.S. Open - back before he'd won a major trophy - that Federer failed to break an opponent's serve once in a Grand Slam match.
Wawrinka, who will play 14th-seeded Jo-Wilfried Tsonga of France in the semifinals Friday. Tsongabeat No. 5 Kei Nishikori 6-1, 6-4, 4-6, 3-6, 6-3.
In the women's drawl, No. 7 Ana Ivanovic advanced to a semifinal matchup against No. 13 Lucie Safarova. Safarova beat Garbine Muguruza 7-6 (3), 6-3 to reach the second major semifinal of her career. Ivanovic reached her first Grand Slam semifinal since winning the 2008 French Open by defeating Elina Svitolina of Ukraine 6-3, 6-2.
