STANFORD, Calif. — American Varvara Lepchenko surprised top-seeded Caroline Wozniacki 6-4, 6-2 in the second round of the Bank of the West Classic on Thursday night.
The fifth-ranked Wozniacki, the Danish player reached the round of 16 at Wimbledon, became the fourth-seeded player to drop out and the second No. 1 seed. Top-ranked Serena Williams pulled out with an elbow injury on the eve of the draw.
The 60th-ranked Lepchenko reached the quarterfinals after failing to get out of the first round in her last seven events. She beat a top-20 opponent for the first time this year and knocked off a top-five opponent for the third time in her career.
