EASTBOURNE, England (AP) — Former champions Caroline Wozniacki and Ekaterina Makarova headed in different directions in the Aegon International quarterfinals on Thursday.
Wozniacki, champion in 2009, held off a strong challenge from Camila Giorgi of Italy 6-7 (7), 6-4, 6-2.
Makarova, the 2010 champ from Russia, fell to fifth seed Angelique Kerber 6-2, 6-1, with the German avenging her second-round defeat to Makarova last year.
Meanwhile, 2011 Wimbledon champ Petra Kvitova withdrew with a right hamstring injury but expects to play in Wimbledon next week.
Wozniacki and Giorgi were interrupted in the second set when a spectator was removed from the stands on a stretcher as Giorgi led 4-3 on serve. When play resumed, Giorgi failed to win a break point to lead 5-3 and Wozniacki went on to win three straight games to level at one-set all.
Wozniacki remained under pressure in the final set, fighting off two break points before breaking to lead 2-1. A double-fault at 4-2 left Wozniacki serving for victory, and in sight of her first title since October.
"It feels good," Wozniacki said of her win. "Game feels in really good shape. Camila played really well. I really had to be focused out there."
Kerber fought off four break points just to hold for 1-1 before taking charge against Makarova, breaking twice to take the set. In the second set, she needed four break points to win the first game before once more dominating Makarova.
"It was not as easy as the score said, because there were tough rallies," Kerber said. "She's a great player on grass, so I was just focusing on me, trying to be aggressive and take my chances. I did a good job."
