NEW HAVEN: Top seed Svetlana Kuznetsova and two-time major champion Amelie Mauresmo and got off to successful starts at the WTA Pilot Pen tournament on Monday.

Mauresmo stopped Japanese ace Ai Sugiyama 6-4, 6-1 in the first round and Russian Kuznetsova beat China's Zheng Jie 6-1, 6-7 (5/7), 6-4.

In the final US Open tune-up tennis event, Mauresmo moves on to face the winner of a match between American Meghann Shaughnessy and Alona Bondarenko.

World number six Kuznetsova easily won the first set but lost the second in a tiebreak and then rallied from a 3-1 deficit in the third to win the match.

The eighth-seeded Mauresmo needed 80 minutes to dispatch Sugiyama, hammering three aces and winning 68 percent of her first-serve points. She also committed seven double faults.

On the men's side of the draw sixth-seeded American Sam Querrey outlasted Frenchman Marc Gicquel 6-4, 6-7 (3/7), 6-2 to reach the third round.
