Fourth-seeded Marion Bartoli was an easy round winner Monday at the $618,000 New Haven Open, a final hardcourt U.S. Open tuneup.

The French Bartoli, a Wimbledon semifinalist last month, handled Aussie Anastasia Rodionova 6-1, 6-4 at the Connecticut Tennis Center at Yale University.

Sixth-seeded Svetlana Kuznetsova was ousted by American Christina McHale in straight sets 7-5, 6-3.

The two-time Grand Slam champion Kuznetsova titled here in 2007

Fifth-seeded Pole Agnieszka Radwanska cruised into the second round with a 6-1, 6-2 pasting of Russian Ekaterina Makarova. Radwanska titled at a U.S. Open Series event in Carlsbad three weeks ago.

Eighth-seeded Anastasia Pavlyuchenkova reached the round of 16 with a 3-6, 6-4, 6-3 come-from-behind victory over qualifier and fellow Russian Vera Dushevina, while Italian Roberta Vinci continued her fine 2011 season with a 3-6, 6-3, 6-3 decision against Czech Lucie Hradecka.

Slovenian Polona Hercog drove out 2010 New Haven runner-up Nadia Petrova 7-5, 7-5 on Day 2. Petrova lost to Danish star Caroline Wozniacki in last year's finale here.

In the final match of the day, Russian Maria Kirilenko outlasted Sara Errani of Italy, 7-5, 7-5. Kirilenko was down 3-4 in the second set before rallying to finish off Errani in two hours, 20 minutes.

Additional opening-round wins came for Spaniards Anabel Medina Garrigues and lucky-loser Carla Suarez Navarro and Czech qualifier Petra Cetkovska.

This week's top seeds are the world No. 1 and three-time reigning champion Wozniacki and French Open winner and Australian Open runner-up Li Na.

The 2011 New Haven titlist will earn $103,000.
