STANFORD, Calif. — Serena Williams spent more time waiting for her quarterfinal match to start than she did on the court against Patty Schnyder. Neither activity proved to be too stressful for the top seed.

Williams advanced to the semifinals of the Bank of the West Classic with little trouble Friday, beating the fifth-seeded Schnyder 6-3, 6-1 in just 54 minutes.

The match began more than an hour later than scheduled because Ai Sugiyama needed 2 hours, 44 minutes to win her quarterfinal over Dominika Cibulkova 6-7 (4), 7-6 (5), 5-3, retired. Cibulkova stopped playing because of cramping in her left leg with Sugiyama serving at 40-0 for the match.

Williams will take on qualifier Aleksandra Wozniak in the semifinals today. Wozniak beat Samantha Stosur 6-2, 5-7, 6-4.
