Istanbul - Wimbledon champion Petra Kvitova of the Czech Republic added the WTA Championships to her increasingly impressive CV on Sunday beating Victoria Azarenka of Belarus 7-5, 4-6, 6-3 in the final.
Kvitova's win means the 21-year-old will rise from third to number two in Monday's new rankings, with current leader Caroline Wozniacki - still yet to lift a major crown - firmly in her sights.
Kvitova also became the first Czech to win the end of season tournament since Jana Novotna in 1997 as she ended a glorious season which has seen her rise from 34th in the world at the start of the year.
She now turns her immediate ambitions to leading her country in next week's Fed Cup final against Russia Moscow after pocketing $1.75 million for Sunday's success.
