MASON, Ohio — Wimbledon champion Roger Federer has withdrawn from the Western & Southern Open, which he has won seven times.
Tournament officials announced Federer’s withdrawal on Monday, the first full day of matches at the event in Cincinnati.
The 19-time major champion says he “tweaked” his back last week at the Rogers Cup, where he lost Sunday to Alexander Zverev in the final.
The Swiss star, No. 3 in the ATP Tour rankings, becomes the fifth of the top six players to skip Cincinnati because of injuries. He joins top-ranked Andy Murray, No. 4 Stan Wawrinka, fifth-ranked Novak Djokovic and sixth-ranked Marin Cilic, the defending champion.
Federer’s withdrawal means Rafael Nadal will return to No. 1 when new ATP rankings are released on Aug. 21. The Spaniard will be No. 1 for the first time since July 6, 2014.
Nadal has spent 141 weeks as the men’s No. 1 player.
MONACO — Dominic Thiem saved a match point and beat Andrey Rublev of Russia 5-7, 7-5, 7-5 in the second round of the Monte Carlo Masters on Tuesday.
Rublev was serving for the match at 5-4, 40-30 but hit a forehand narrowly wide. Fifth-seeded Thiem broke him with backhand pass down the line and held for 6-5.
The Austrian was 15-40 up on Rublev’s serve and clinched victory on his first match point, when Rublev double-faulted with a weak serve into the net.
“I was 10 centimeters from being out of the tournament,” a relieved Thiem said. “But I’m happy that I played two hours and 40 (minutes).”
Thiem has reached the French Open semifinals for the past two years. He next meets 12-time Grand Slam champion Novak Djokovic or Borna Coric of Croatia, who play their second-round match on Wednesday.
“I’m looking forward to watching Djokovic and Coric in front of the TV, and then playing the winner on Thursday,” Thiem said.
In the second round later Tuesday, fourth-seeded Grigor Dimitrov of Bulgaria faced Pierre-Hugues Herbert and seventh-seeded Lucas Pouille played Mischa Zverev.
In remaining first-round play, there were wins for Gilles Simon of France, Marco Cecchinato of Italy and Jan-Lennard Struff of Germany.
MONACO — Jared Donaldson has been fined $6,200 for unsportsmanlike conduct after angrily ranting at the chair umpire during his first-round loss to Albert Ramos-Vinolas at the Monte Carlo Masters.
The American became irate with a call when Ramos-Vinolas was serving at 3-2, 40-0 in the second set on Monday. Donaldson thought the serve was out and pointed to the ground, shouting, “There’s a mark right here,” and then screaming the same words in the face of French umpire Arnaud Gabas.
He then squared up to Gabas and shouted: “Yes it is, yeah it is,” as he insisted his mark was right and the umpire’s call of in was wrong.
Donaldson, who yelled again at Gabas before the supervisor came on, received a code violation. He lost 6-3, 6-3.
