NEW HAVEN, Conn. (AP) — Top-seeded Sara Errani fell to Russia’s Ekaterina Makarova 7-5, 6-1 on Wednesday at the New Haven Open.
Errani, ranked No. 5 in the world, became the fifth of the tournament’s eight seeds to lose in the first two rounds of the final WTA tuneup before next week’s U.S. Open.
“The good thing is that if you lose, you have more time to prepare there, if not, you have more confidence,” Errani said. “I hope the court there will be different.”
Caroline Wozniacki became the first seeded player to make it to the quarterfinals, beating Karin Knapp 6-1, 7-5.
The fourth seed cruised through the first set, then fought through some health issues to hold on for the win. Up 3-2 in the final set, the Danish star, who has been battling a cold this week, called for a trainer after experiencing some dizziness in the 90-degree temperatures. She dropped the next two games before rallying.
“I’m definitely feeling much better,” she said after the match. “I was feeling worse in the beginning of the week.”
Wozniacki is trying for her fifth title in the six years she has played in New Haven. Her lone loss came last year in the semifinals when she had to retire because of a knee injury.
Errani didn’t make it through her first match, after receiving a bye in the first round. She had trouble with her slow, spinning serves all afternoon and was broken four times by Makarova.
The 25-year-old Russian dominated her own service games, was broken just once and had eight aces.
“Today was a good day for me and all my shots was working really good,” Makarova said. “I understood a little bit more how to play against her.”
Makarova will play Simona Halep in the quarterfinals.
Halep didn’t have a WTA title before this year, but has three this summer and is 28-5 in her last 33 matches. She dropped her first set Wednesday but bounced back for a 3-6, 6-4, 6-1 win over Carla Suarez Navarro of Spain.
The 21-year-old Romanian also attributed her slow start to the 90-degree heat, which she said caused to alter her game plan in the second set.
“I played more offensive, more aggressive and I just tried to finish the point very fast,” she said.
Defending champion Petra Kvitova and American Sloane Stephens each had second-round matches scheduled later Wednesday.
