Former champion Petra Kvitova became the first player to reach the quarterfinals at this year's Wimbledon, beating Carla Suarez Navarro of Spain 7-6 (5), 6-3.
Kvitova served for the first set at 6-5 but was broken at love and then lost four straight points in the tiebreaker to trail 4-3. But she capitalized on a couple of errors by the Spaniard and converted her first set point when Suarez Navarro netted a backhand.
In the second, she broke to lead 4-2, and served out the match at love when Suarez Navarro sent a forehand long.
The 18th-ranked Suarez Navarro was the first Spanish woman since 2001 to reach the fourth round at the All England Club.
In a busy day at Wimbledon, all remaining men and women were set to play their fourth-round matches.
