Singapore: Maria Sharapova's chances of claiming the season-ending No. 1 ranking were hurt Tuesday after a 7-6 (4), 6-7 (5), 6-2 loss to Caroline Wozniacki at the WTA Finals.
Sharapova had 15 double-faults, including two while serving for the first set, and 76 unforced errors. Wozniacki finished the match, which has 12 breaks of serve, with 35 unforced errors.
It was Wozniacki's second straight victory over Sharapova. The Dane also won in the fourth round of this year's US Open.
