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.
KEY BISCAYNE, Fla. (AP) Caroline Wozniacki has reached the quarterfinals of the Miami Open, advancing Monday when Garbine Muguruza retired after one set with a heat-related illness.
Wozniacki, the sixth seed, took that set over the 12th-seeded Muguruza 7-6.
Muguruza was tended to by doctors following that tiebreaker, which wrapped up a 70-minute set, and decided she could not continue on a 77-degree, humid afternoon.
Wozniacki still has not dropped a set in the tournament, and will face fourth-seeded Dominika Cibulkova or Lucie Safarova in the quarterfinals.
Earlier Monday, Karolina Pliskova also reached the quarterfinals, beating Czech Fed Cup teammate – and occasional doubles partner – Barbora Strycova 6-1, 6-4. Pliskova needed only 21 minutes to take the first set, winning 11 consecutive points in one stretch and 16 of 17 on her serve.
KEY BISCAYNE, Fla. (AP) Milos Raonic has pulled out of the Miami Open after aggravating a right hamstring injury that sidelined him for nearly a month.
The No. 3-seeded Raonic withdrew before Sunday’s match against American qualifier Jared Donaldson, who advanced to the fourth round.
Raonic said his injury became progressively worse after his opening match, his first since Feb. 25. He expects to be sidelined at least two weeks and perhaps longer.
The Canadian said he hasn’t made it through an entire tournament healthy since Wimbledon last July.
