Two seeds pass first round test; one seed retires due to heat illness

On Monday in New Haven, Connecticut, the seeds had a tough day, as two seeds won their debut matches and one seed fell in the first round.

Patty Schyder and Alize Cornet were the seeds who won. The Swiss, seeded fifth, was pushed to the limits by American Jill Craybas, but she eventually won the match, 64 76(2); Cornet, seeded seventh, needed strength to survive her match against Nicole Vaidisova, to win 63 76(8). Cornet won to Vaidisova in the first round of the Olympics, which was an advantage.

Dominika Cibulkova was unlucky on Day 1, as she lost the first set to Dane Caroline Wozniacki 76(7), before retiring due to heat illness in the first game of the second set.
