MOSCOW (AP) Former Grand Slam champions Ana Ivanovic and Samantha Stosur made the Kremlin Cup quarterfinals with straight-sets victories on Thursday to set up a rematch of last year's semifinal.
The former top-ranked Ivanovic beat Klara Zakopalova of the Czech Republic 6-3, 6-1, while 2011 U.S. Open winner Stosur extended her winning streak to seven matches by beating Alize Cornet of France 6-4, 6-1 in the second round.
Meanwhile, men's top seed Richard Gasquet, making his debut in Moscow, advanced to the quarterfinals with a 6-3, 3-6, 6-1 victory over Evgeny Donskoy of Russia.
The fourth-seeded Ivanovic led 5-0 in the first set, traded early breaks in the second and rolled the rest of the way.
"It wasn't an easy match for me," Ivanovic said. "I really started well. But she's a tough player and the second set was much tougher that the scoreline indicates. But I added power in the important moments and was very pleased to win."
