EASTBOURNE, England - Caroline Wozniacki shook off a disappointing first set in the quarterfinals of the Aegon International on Thursday to get past Camila Giorgi and avenge a loss to her in their last meeting.
The eighth-seeded Wozniacki had a 6-3 lead in the first set tie-break against Giorgi but couldn't hold on. She maintained her composure, though, and down 4-3 in the second set held, broke and held again to force a decider. There, she broke twice en route to a 6-7(7), 6-4, 6-2 win.
Break point opportunities were key, as Wozniacki was four of five on Giorgi's serve and saved seven of eight on her own serve.
"It was a really tough match," Wozniacki said. "Camila played really well. I really had to be focused out there. She hits the ball very hard and flat and has some good serves. This was a good win for me."
Wozniacki had fallen to Giorgi, who is no stranger to upset wins, in three sets in their most recent encounter in the third round of last year's US Open. Next up for the 2009 Eastbourne champion is Angelique Kerber, whom she is 3-4 against.
Advancing by the exact same score was Madison Keys over fellow American Lauren Davis. Keys had lost to Davis in a third set tie-break in their most recent clash earlier this year in Miami. She has now matched her best WTA outing - semifinal showings in Osaka in 2013 and Sydney and Strasbourg this year - but this will be her first semifinal appearance on grass.
Keys' opponent in that semifinal will be another WTA Rising Star, British No.1 Heather Watson.
"We know each other really well," Keys said. "We played each other last year at Wimbledon. It was a close match. She's obviously been playing very well. I think it will be a really close match."
Watson got through her quarterfinal by virtue of a walkover because of a right leg injury suffered by No.2 seed Petra Kvitova.
"I started to feel it yesterday morning, but I still played a solid match," Kvitova said. "However, it felt much worse today. I hope I'll be ready for Wimbledon."
"It's a shame that Petra is injured," Watson said. "I hope she gets well for Wimbledon, but obviously I'm glad to be through to my first semifinal here in Eastbourne and look forward to my next match."
