Nadal ousted, Serena drops out
BEIJING — Rafael Nadal was knocked out of the China Open on Friday in his third match back from an extended injury layoff, falling to big-hitting qualifier Martin Klizan 6-7 (7-9), 6-4, 6-3.
The second-seeded Spaniard struggled with Klizan's power game and his own consistency in the quarterfinal, finishing with 37 unforced errors and just 21 winners.
Nadal said an upset like this was natural "when one player plays bad, plays without rhythm, no confidence on the shots, having more mistakes than usual, being not confident how to play the points, and how to win the points."
Klizan, ranked 56th, said: "For me, this victory was the best night in my life. I'm just very happy that I beat a legend."
Novak Djokovic and Andy Murray set up a semifinal showdown with convincing wins over two young players enjoying breakthrough years. The top-seeded Djokovic defeated Wimbledon semifinalist Grigor Dimitrov 6-2, 6-4 and No. 6 Murray took out U.S. Open champion Marin Cilic 6-1, 6-4.
On the women's side, defending champion Serena Williams withdrew before her quarterfinal against Samantha Stosur with a left knee injury that raised doubts about her ability to play the WTA Finals in Singapore this month. Williams said the pain was so bad in her knee during Thursday's three-set win over Lucie Safarova, she had no choice but to pull out.
"It throbs just sitting, standing," she said. "I felt it mostly serving because I'm landing on my left knee. That was really killer for me."
