PERTH  - World number two Petra Kvitova continued her imposing start to the year to give the Czech Republic the lead in the Hopman Cup final against France in Western Australia on Saturday.

Unbeaten in her three previous singles matches in Perth, including beating world number one Caroline Wozniacki on Friday, Kvitova was too good for ninth-ranked Marion Bartoli in the women's singles, winning 7-5, 6-1.

"I am happy that I won and we lead 1-0," Kvitova said after the match, the first of three in the tie, which also includes men's singles and mixed doubles. I was more aggressive on the return and was tougher on my serve."

Bartoli, 27, was up a break at 5-3 in the opener and served for the set, but last year's Wimbledon champion turned on the quality to reel off the next seven games and seize control.

She hammered a forehand winner from the Bartoli serve to seal the first set after 59 minutes, and the 21-year-old continued in the same blistering form to earn an early break in the second set.
