CINCINNATI, Aug 17: Ashleigh Barty edged closer to a return to the top WTA ranking, reaching the WTA semifinals as current number one Naomi Osaka retired with a knee injury.
Barty, the Australian top seed, on Friday engineered her second comeback in as many days, overhauling Maria Sakkari 5-7, 6-2, 6-0.
But the US Open alarm bells were ringing for Osaka less than two weeks before the start of her title defense at Flushing Meadows after a left knee injury saw her retire against Sofia Kenin � sending the American into the semis with a 6-4, 1-6, 2-0 victory.
Men�s top seed Novak Djokovic also had the trainer on during his 7-6 (7/2), 6-1 victory over Lucas Pouille, but hoped discomfort in his right elbow wouldn�t linger.
The 16-time Grand Slam champion will next face Daniil Medvedev, who beat Russian compatriot Andrey Rublev, conquerer this week of Roger Federer, 6-2, 6-3.
Osaka�s left knee trouble was more of a concern, the Japanese star admitting it put a cloud over her upcoming US Open title defense.
Osaka had won the second set to level the match when she first complained of apparent knee pain and after one game of the third set called for the physio. With the knee heavily taped Osaka played one more game before packing it in and sending Kenin to the semis.
�This is not the way I wanted to win,� said Kenin, who will next play fellow American Madison Keys, a 6-2, 6-3 winner over Venus Williams.
French Open champion Barty will play for a place in the final against Russian veteran Svetlana Kuznetsova, who beat third seed Karolina Pliskova 3-6, 7-6 (7/2), 6-3 to end the Czech�s chances of claiming the number one ranking next week.
Serving for the match at 5-4 in the second set, Pliskova was broken. Kuznetsova dominated the ensuing tiebreaker and took charge in the third set as Pliskova began to fade.
Barty said a potential return to number one wouldn�t be her focus this weekend.
Gasquet won his last contest at this level in Miami in 2013 and had since lost seven Masters quarterfinals.
He will play for a place in the final against 16th seed David Goffin, who advanced in a walkover against Japanese qualifier Yoshihito Nishioka, who could not take the court due to illness. � AFP
