TOKYO — A resurgent Caroline Wozniacki advanced to the second round of the Pan Pacific Open on Tuesday while gaining revenge over Belinda Bencic for last year’s semifinal defeat.
Continuing the form that took her to the U.S. Open semifinals, Wozniacki hit 10 aces in the 6-2, 5-7, 6-1 win over Bencic to set up a second-round meeting with fourth-seeded Carla Suarez Navarro.
The result ended a run of four straight defeats for Wozniacki against the Swiss player.
Yulia Putintseva of Kazakhstan upset fifth-seeded Madison Keys of the United States 6-3, 3-6, 7-6 (7) while facing down 15 aces, and sixth-seeded Dominika Cibulkova of Slovakia ousted Lucie Safarova of the Czech Republic 4-6, 6-1, 7-5 on a drop shot after 2 1/2 hours.
The 2013 champion Petra Kvitova of the Czech Republic beat Madison Brengle of the United States 6-3, 6-3 to set up a meeting in the second round with Rio de Janeiro Olympic champion Monica Puig of Puerto Rico.
ATLANTA — Second-seeded John Isner beat Canada’s Vasek Pospisil 6-3, 6-4 on Wednesday night in the 6-foot-10 former University of Georgia star’s opening match in the BB&T Atlanta Open.
Coming off a victory Sunday in the Hall of Fame Open in Newport, Rhode Island, Isner is seeking his fourth Atlanta title in five seasons. He lost to Nick Kyrgios in the final last year.
Isner set up a quarterfinal match at Atlantic Station against Slovakia’s Lukas Lacko, a 6-3, 6-1 winner over sixth-seeded Donald Young. The American has 11 career titles, all at the ATP World Tour 250 level.
Third-seeded Gilles Muller of Luxembourg and Tommy Paul also reached the quarterfinals. Muller beat France’s Quentin Halys 6-4, 6-7 (1), 6-3, and Paul topped Tunisia’s Malek Jaziri 6-7 (5), 6-4, 6-3.
In the top half of the draw, top-seeded Jack Sock will open play Thursday with a second-round match against Israel’s Dudi Sela.
NEWPORT, R.I. — Top-seeded John Isner beat Australian qualifier Matthew Ebden 6-3, 7-6 (4) on Sunday for his third Hall of Fame Open title.
The hard-serving American also won the grass-court event in 2011 and 2012. He has 11th career titles, all at the ATP World Tour 250 level.
“It’s hard to win a tournament,” Isner said. “It’s no small feat to come out here and be the last man standing. I’m very happy about that. It’s been two years since I won a tournament, so I had that weighing on my mind.”
Isner became the second player to win an ATP title without facing a break point since records began in 1991. Tommy Haas also accomplished the feat in Memphis, Tennessee, in 2007.
“I’m very happy with how I played all week,” Isner said. “It was a perfect week and I couldn’t ask for anything better.”
Ebden was playing his first tour-level final.
“It’s a lot of reward for a lot of hard work, a lot of years of sacrifice,” Ebden said. “It’s disappointing, but at the same time I have to be happy with my week.”
