MARSEILLE, France (AP) Second-seeded Stan Wawrinka hobbled out of the Open 13 second round after retiring when trailing 6-4, 1-1 against Ilya Ivashka on Thursday.
It was not immediately clear why Wawrinka abandoned against the 193rd-ranked Belarusian, but the three-time Grand Slam champion still appears to be struggling with his troublesome left knee and looked upset as he left the court. This loss follows the 32-year-old Swiss player’s unexpected first-round defeat to 259th-ranked Dutchman Tallon Griekspoor at the ABN AMRO World Tournament in Rotterdam last week.
Ivashka advances to the quarterfinals against Frenchman Nicolas Mahut, who upset sixth-seeded Gilles Muller of Luxembourg 3-6, 6-2, 6-4.
Meanwhile, Tomas Berdych rallied to reach the last eight. The fourth-seeded Czech labored to a 5-7, 7-6 (4), 6-3 win against unheralded Italian Stefano Travaglia, who had 18 aces. Berdych next plays seventh-seeded Damir Dzumhur of Bosnia-Herzegovina
Eighth-seeded Filip Krajinovic of Serbia and ninth-seeded Russian Karen Khachanov also advanced, but far more easily in straight sets.
Krajinovic won 6-3, 6-3 against French veteran Gilles Simon. Krajinovic was a surprise runner-up at the Paris Masters in November after coming through the qualifiers, and he next faces third-seeded Frenchman Lucas Pouille.
The 21-year-old Khachanov was in clinical form in a 6-2, 6-1 win against Mischa Zverev, taking all four of his break-point chances on the German player’s serve.
He next plays 36-year-old Frenchman Julien Benneteau.
STUTTGART, Germany (AP) Roger Federer defeated Milos Raonic 6-4, 7-6 (3) to mark his return from three months off with the Stuttgart Open title on Sunday.
The Swiss great, who is assured of reclaiming the No. 1 ranking from Rafael Nadal on Monday, broke at 1-1 in the opening set and held his nerve in the second, where Raonic double-faulted.
Federer skipped the entire clay-court season for the second year in a row, but he wrapped up his 18th grass-court title in 1 hour and 18 minutes – his 98th title overall and third of the season after victories at the Australian Open and World Tennis Tournament in Rotterdam.
“It’s a wonderful feeling. I fought hard. When you finally manage it, the joy is even greater,” said Federer, who extended his grass-court winning streak to 16 matches including his titles at Halle and Wimbledon last year.
The 36-year-old will need to defend his title at Halle to maintain his No. 1 spot ahead of Wimbledon.
LONDON (AP) Andy Murray has confirmed he will make his return to competitive tennis at the Queen’s Club tournament next week after almost a year out injured and faces Nick Kyrgios in his opening match.
The three-time major winner has not played since last year’s Wimbledon due to a hip injury and subsequent surgery.
Murray practiced at Queen’s on Friday ahead of next week’s grass-court Fever-Tree Championships, delayed a decision until Saturday and then told tournament officials he would be there.
“Andy Murray has confirmed that he will play,” the tournament said on its official Twitter account.
Murray has a good record against 24th-ranked Kyrgios, winning all five of their meetings.
French Open champion Rafael Nadal withdrew Wednesday from Queen’s in an attempt to be ready for Wimbledon.
Queen’s is one of the main warmup tournaments for Wimbledon, which begins on July 2.
