Kvitova caps breakthrough year

Wimbledon champion Petra Kvitova clinched the WTA Championships with a 7-5, 4-6, 6-3 victory over Victoria Azarenka in Istanbul. The victory moves the Czech ahead of Maria Sharapova to second in the world.

“When I started this season we didn’t have a goal,” said Kvitova after claiming a cheque for £1.1m. “We just wanted to improve my game and now I am No2 and Wimbledon champion. It’s just a dream.”
