Like Wozniacki, Kvitova's first half of the season is totally forgettable. However, she turned it on for Wimbledon, dominating her matches to win in style. With her confidence back, she went further by adding titles in New Haven and Wuhan. A recent finalist in Beijing, her form coming into Singapore is stellar. She has a chance to end the year number one depending on how Serena and Sharapova performs. Great turnaround for someone who has been ousted from Melbourne in the first round.
Kvitova doesn't need to overthink much. Her game is pure power, there is no need for cute drop shots or lobs. If she's on, she's unplayable, as evidenced in the Wimbledon final. Petra's fitness is also an asset, having won numerous three set matches, but mostly due to her lapse in concentration during matches. Lately, she has been able to harness her power to great effect. If she continues her free hitting, she might just add another tour championships to her resume.
Chances of winning Singapore: 80%
There is no doubt Petra's game works well on fast surfaces. Given the quick indoor surface of Singapore, she will thrive and be able to dominate with her laser like ground strokes. However, it remains to be seen if she can overcome the top 2 seeds. She has never beaten Serena before, and hasn't beaten Sharapova since 2011. If she can overcome that, she can be the trophy holder at the end of the week.
