The Czech Petra Kvitova confronts the Spanish Carla Suarez Navarro in the quarterfinals of New Haven, Connecticut, tournament on August 23, 2018Maddie Meyer
Czech Petra Kvitova had to retire Thursday in the quarter finals of the New Haven-tournament due to a left shoulder injury that could endanger her chances on the US Open from Monday.
Kvitova, fifth in the world, lost the first round (6-3) of her match against the Spaniard Carla Suarez Navarro (N.30) and decided to throw the towel in the ring.
"I felt pain over the shoulder, already in my game on Wednesday, I felt something, it got worse, I tried my luck in the first set, but it was wrong in my feeling," explained Kvitova, crowned three times in New Port.
"I could not serve as well as I wanted, if you play a girl like Carla, you can not afford to play, I do not know how much of what you can do normally is too difficult," she said.
Last week Kvitova had reached the last four of the Cincinnati tournament, where she lost to future winner Kiki Bertens of the Netherlands.
The Czech, whose best result at the US Open is to reach the quarterfinals in 2015 and 2017, faces the first round of the New York tournament, the Belgian Yanina Wickmayer.
Carla Suarez Navarro, for his part, will face Friday in the semi-finals of Puerto Rican Monica Puig, who contributed the dust to French Caroline Garcia, sixth in the world.
Puig, the result of qualifying and returning from a hip injury that robbed him a good part of the seasons from clay and turf, won 7-5, 1-6, 6-2.
"Since Wimbledon I feel physically better," said the Olympic champion 2016, 72nd in the WTA ranking.
The second semifinal sees the Belarusian Aryna Sabalenka (N.25), who confirmed her beautiful summer by defeating Belinda Bencic from Switzerland (6-3, 6-2), the German Julia Görges (N.9), victorious Rus Ekaterina Makarova (6-4, 6-2).
