NEW HAVEN, Conn. (AP) — Top-ranked Caroline Wozniacki remained undefeated at Yale, advancing to the semifinals of the New Haven Open on Thursday with a 7-5, 6-3 win over 19-year-old American Christina McHale.
Wozniacki is 15-0 at the WTA’s final tuneup before the U.S. Open and is the tournament’s three-time defending champion.
She broke McHale, playing in her second career quarterfinal match, to win a close first set, and again in the eighth game of the second set.
Li Na endured several hours of rain delays and three sets of tennis before advancing in her quarterfinal, 6-4, 3-6, 6-2, over Russia’s Anastasia Pavlyuchenkova. Li will play Czech qualifier Petra Cetkovska who beat fourth-seed Marion Bartoli 7-5, 7-5.
Wozniacki will face third-seeded Francesca Schiavone, who advanced when Anabel Medina Garrigues withdrew due to a knee injury.
