Caroline Wozniacki is seeking a record fifth WTA New Haven title but she faces strong competition from Agnieszka Radwanska and Petra Kvitova.
Wozniacki equalled Venus Williams' record last year by winning her fourth consecutive New Haven title but even the great American didn't manage to win it five times on the bounce. Can Wozniacki succeed where she failed ?
Her recent form has been promising, she reached the Montreal semi-finals earlier this month, pushing eventual champion Kvitova close but with the field containing ten players inside the world's top 20, it will be extremely challenging for Wozniacki.
Sara Errani is in the form of her life after reaching the French Open final in June and the durable Italian could be a threat this week.
And there's also the in-form duo of Maria Kirilenko and Lucie Safarova. Kirilenko may have lost in the first round of Cincinnati to Venus but the Russian has been playing some exceptional tennis recently, making the quarters at Wimbledon and the semis of the Olympics. And Safarova was extremely unlucky not to make the Montreal final, blasting her way to the last four and leading Li Na 5-1 in the deciding set in their semi-final before losing the last six games in a row.
