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.

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.
