Defending champion Petra Kvitova of the Czech Republic advanced to the Connecticut Open quarterfinals, beating Canada's Eugenie Bouchard 6-3, 6-2 Wednesday night. Kvitova, the two-time Wimbledon winner and a bronze medalist in the Rio Olympics, won 10 straight games after falling behind 3-1 in the first set. She will face Ekaterina Makarova of Russia. Makarova won her second-round match Tuesday. Belgium's Kirsten Flipkens beat France's Caroline Garcia 7-6 (3), 7-5 to set up a match against top-seeded Agnieszka Radwanska of Poland. Radwanska advanced Tuesday. "It came all to a few points today," said Flipkens, a winner over Venus Williams in Rio. "It could have gone her way as well." Second-seeded Roberta Vinci of Italy topped Croatia's Ana Konjuh 6-2, 6-2. Vinci will face Sweden's Johanna Larsson, a 7-6 (1), 6-4 winner over American Shelby Rogers 7-6 (1), 6-4. The 18-year-old Konjuh is ranked 100th in the world and had to get through three rounds of qualifying to reach the main draw at the New Haven. At the beginning of the match, Konjuh had two break points on Vinci's serve, but the Italian second seed held on. Konjuh double faulted twice in the sixth game, helping Vinci break serve at love in the sixth game for a 4-2 lead. Vinci then seized control of the match. Gasquet wins all-French affair Top seeded Richard Gasquet defeated French compatriot Stephane Robert in straight sets 6-1, 6-3 to reach the quarterfinals of the ATP Tour's Winston-Salem Open Wednesday. Gasquet saved seven of eight break points and broke the unseeded Robert's serve five times in the hardcourt tournament in North Carolina. "I've known Stephane for a long time now, so I know how dangerous he can be," Gasquet said. "He likes to play close to the baseline. We've practised together often, so I know his game and he knows mine. I didn't make many mistakes today, and that was the difference." Gasquet will next face Australia's John Millman, who came from behind to win 5-7, 6-0, 6-3 against wild card Bjorn Fratangelo. Taiwan's Lu Yen-hsun advanced to his fourth straight Winston-Salem quarterfinal with a 6-4, 6-0 win over Argentina's Diego Schwartzman. "Fortunately I played really well on game points and on break points," Lu said. "My serve was there when I needed it, and that helped me a lot today." Next up for Lu will be number two seed Roberto Bautista Agut, of Spain, who defeated Cyprus' Marcos Baghdatis 4-6, 6-3, 6-1. Fifteenth-seeded Fernando Verdasco fired 10 aces as he rolled over fourth seeded American Steve Johnson of the Unites States 6-4, 7-6 (9/7). In the quarterfinals, Verdasco will face Serbia's Viktor Troicki, who toppled American Sam Querrey 6-2, 7-6 (7/5). Andrey Kuznetsov of Russia advanced when Jiri Vesely of the Czech Republic retired at 5-5 in the first set.
