Former top-10 player Vera Zvonareva routed fifth-seeded Jelena Jankovic 6-1, 6-1 in 43 minutes in the quarterfinals of the Western & Southern Financial Group Women's Open on Friday.
Fourth-seeded Katarina Srebotnik of Slovenia also reached the semifinals, for the first time in 14 tournaments this season, with a 6-2, 6-1 win over sixth-seeded Marion Bartoli of France.
Srebotnik will play either top-seeded and defending champion Patty Schnyder or ninth-seeded Sania Mirza of India. Zvonareva, who lost to Lindsay Davenport in the tournament's 2004 final, had 15 winners and just four unforced errors.
"I expected a really tough match, a lot of long rallies," said Zvonareva, ranked 50th.
"Maybe she wasn't at her best. It was important for me to stay in the match from the first point to the last. I think I'm just lucky that it went so smoothly all through the match. To win like this just feels great," she said.
Jankovic won only 10 points on her service games. Both games won by the Serb came from breaks.
"I couldn't find my rhythm, and she played very well," Jankovic said. "She didn't make many mistakes. She was solid, and I couldn't put it in the court."
Zvonareva, who struggled last year with injuries to her left ankle and right shoulder, reached the semifinals for the third time in 16 tournaments this year. She will play the winner between Amy Frazier and Serena Williams on Saturday.
Srebotnik dominated Bartoli with nine aces and 31 winners.
