SHANGHAI – Japanese ace Kei Nishikori, ranked a personal best 15th after winning the Japan Open for his second career title on Sunday, was handed a 2-6, 6-1, 6-4 second-round defeat by Sam Querrey at the Shanghai Masters on Wednesday.
The 14th-seeded Nishikori breezed through the first set but lacked the same sharpness after undergoing treatment on his right ankle at the end of the set.
Still, after Querrey had leveled up the match, Nishikori looked to be in a good position to advance, taking a 4-1 lead in the third set, only to lose five games in a row from the sixth.
“I had some serious pain in my right ankle. It hurt all the way through the Japan Open and hurt yesterday and today. My left knee also hurt,” said Nishikori, whose young career has been interrupted by a number of injuries.
“If I am honest my whole body is tired. Today I also played to my absolute limit until the end.”
The 22-year-old Nishikori reached the semifinals in Shanghai last year.
Australian top seed Samantha Stosur rallied from a set down to beat Frenchwoman Virginie Razzano and advance to the quarterfinals of the Japan Women’s Open on Wednesday.
The 2011 U.S. Open champion dropped the first set before coming back to post a 1-6, 6-2, 6-4 in a little under 2 hours at Utsubo Tennis Center in Osaka.
Stosur, runner-up in last year’s final to Frenchwoman Marion Bartoli, will face unseeded Jamie Hampton in the last eight after the American prevailed 7-5, 7-5 against Thai wild card and 2010 champion Tamarine Tanasugarn.
The 28-year-old Stosur is looking to bounce back from the disappointment last week in Beijing of missing out on the eighth and last spot in the WTA Championships.
Li Na ended up securing the spot, and Stosur and Bartoli will be the two alternates in Istanbul, though which one of them is first alternate and which is second will be determined in Moscow next week.
Japan’s Misaki Doi beat Russian qualifier Olga Puchkova 6-3, 6-2.
