NEW HAVEN, CT, USA - The first round wrapped up and the second round kicked off at the Pilot Pen Tennis presented by Schick on Tuesday, with Amélie Mauresmo and Anna Chakvetadze snapping up the first two quarterfinal berths at the Premier-level stop in New Haven, Connecticut.

Eighth seed Mauresmo was the first to reach the round of eight, steamrolling Alona Bondarenko in just 54 minutes, 61 61. Mauresmo found herself at 1-1 in each set but completely pulled away each time to reach the quarterfinals for the ninth time in nine tries, having been a runner-up here once (2005), a semifinalist twice (2003 and 2008) and a quarterfinalist five other times.

Chakvetadze, whose best result in New Haven is a runner-up finish from a year ago, won an all-unseeded duel with Sybille Bammer, 46 64 75. Chakvetadze and Bammer played a week ago in Toronto, with Chakvetadze leading 63 41 before crumbling to the crafty Bammer; but the Russian turned the tables a week later, rallying from 64 20 down to win in two hours and 49 minutes.

The last four first round matches also took the court with No.3 seed Flavia Pennetta routing qualifier Ioana Raluca Olaru, 61 62; No.6 seed Marion Bartoli rallying from a first set loss to beat María José Martínez Sánchez, 46 63 61; No.9 seed Samantha Stosur squandering two set points in the first set tie-break but rallying back to win against Alizé Cornet in three sets, 67(8) 62 64; and, at night, No.2 seed and defending champion Caroline Wozniacki routing lucky loser Edina Gallovits, 60 60.

The remaining six second round matches, including those of No.1 seed Svetlana Kuznetsova and Wozniacki, will take the courts on Wednesday.
