Petra Kvitova, a two-time champion, defeated Romanian Ana Bogdan on Thursday by scores of 6-1 and 7-6 (5) to go to the third round of Wimbledon.
The powerful Czech, who was seeded 25th, had a commanding 6-1, 5-1 lead before Bogdan pulled off an incredible comeback.
When serving at 5-4, Kvitova had a match point, but she was broken for the second time in a row as Bogdan tied the score.
Kvitova served at 5-6 and Bogdan then had two set chances, saving one with an ace and the second with a forehand winner.
Bogdan’s pressed backhand found the net in the tiebreak, giving relief to Kvitova who had been struggling to win.
Kvitova, who won Wimbledon in 2011 and 2014, will now face fourth-seeded Paula Badosa of Spain, who defeated Irina Bara of Romania with ease by scores of 6-3, 6-2.
Kvitova has only ever made it to the Wimbledon fourth round since winning her second championship, but she is in fantastic shape after winning the Eastbourne grasscourt championship last week.
