Roberta Vinci of Italy routed Slovakia's Daniela Hantuchova 6-1, 6-2 on Tuesday in their opening round-robin match at the Tournament of Champions.
The fourth-seeded Vinci dominated throughout, breaking five times to wrap up the win in just 1 hour, 5 minutes. The two traded breaks to start the second set, but the Italian then jumped out to a 4-1 lead to take control.
Top-seeded Caroline Wozniacki was to meet Hsieh Su-wei of Taiwan later Tuesday in the same group of the eight-player tournament.
In the other group, Bulgaria's Tsvetana Pironkova played Zheng Jie of China.
