Davenport is 16-1 in singles since she returned to the tour after the birth of her first child. She is closing in on a third title in the first four tournaments of her comeback.

She beat the unseeded Errani in 57 minutes, hitting 40 winners in 18 games. She stymied her Italian opponent with seven aces.

"I started off a little slow," Davenport said. "She's a tough opponent coming up and she's going to be good.

"I just haven't played much tennis in the past year and I have a few aches and pains in my body. My arm was a bit sore today but hopefully it will all hang together for another couple of days."

Davenport will face 17-year-old Austrian Tamira Paszek, the No. 6 seed, in the semifinals tomorrow. Paszek advanced with a 6-1, 6-3 win over second-seeded Maria Kirilenko of Russia.

"I didn't see much of her game today because it was over pretty quickly, but she looks a good player," Davenport said.
