Wozniacki, Vinci win opening matches in Sofia

Caroline Wozniacki and Roberta Vinci had easy straight-set

victories Tuesday in their first round-robin matches at the

season-ending Tournament of Champions.

The top-seeded Wozniacki defeated Hsieh Su-Wei of Taiwan 6-2,

6-2 in 60 minutes while it took Vinci five minutes longer to rout

Slovakia’s Daniela Hantuchova 6-1, 6-2.

Wozniacki converted all five of her break points and only lost

her serve once, in the second set.

”I always try to finish my matches in two sets and I am happy

that this time it worked,” said Wozniacki, who is coming off

titles in Seoul and Moscow. ”I will try to finish this season with

a hat trick.”

The fourth-seeded Vinci dominated throughout, breaking five

times. The two traded breaks to start the second set, but the

Italian then jumped out to a 4-1 lead to take control.

Wozniacki will play Vinci on Wednesday, with the winner likely

clinching a spot in Saturday’s semifinals. The first two in each

group advance.

In the other group, Bulgaria’s Tsvetana Pironkova came from

behind to dispatch sixth-seeded Zheng Jie of China 2-6, 6-4, 7-6

(4). Pironkova took a 3-0 lead in the third set before being forced

into a tiebreaker.

The Tournament of Champions features the six highest-ranked

players who have won a title during the season but did not qualify

for the WTA Championships, along with two wild cards.

It is the final event on the WTA calendar.
