Two-time Wimbledon champion Petra Kvitova beat Donna Vekic of Croatia 6-2 7-6(6) on Sunday to lift the German Open title and confirm her form on grass just over a week before the Grand Slam in London.
The 33-year-old Czech, who had also beat Vekic en route to the title in Miami this year, was too strong for the Croat in the first set with the 26-year-old struggling with her forehand.
Kvitova found herself a break down early in the second set but battled back from 5-3 and moved 6-5 up with an ace.
Vekic, who has shot up the rankings from 69th to 23rd this season following an Australian Open quarter-final spot and a title in Monterrey, forced a tiebreak.
She was beaten, however, with a thundering Kvitova forehand on the first match point.
