Henin, Williamses, Federer, Roddick advance; Safina derails Davenport

In the quarterfinals, Venus Williams will play Kuznetsova, and Jankovic will meet Elena Dementieva, a 6-3, 6-2 winner over Germany's Sabine Lasicki.

Lindsay Davenport hit a bump in her career comeback when she lost to Dinara Safina 6-3, 6-4.

It was a flat followup to Davenport's win Sunday over No. 2-ranked Ana Ivanovic. That upset victory was the biggest for Davenport since she returned to the women's tour last summer after becoming a parent.

"That's the thing with tennis," Davenport said. "Every day you start over. But hopefully more positives than negatives come from this tournament."

Against Safina, Davenport totaled 34 unforced errors, including six double faults. She hit only 20 winners to 31 for Safina, seeded 13th.

"She did everything better than I did," Davenport said. "I came up against a player today that was real intense and real eager to win."

Safina will face fellow Russian Vera Zvonareva, who defeated Ai Sugiyama 6-2, 6-7 (5-7), 6-0.

Federer, still seeking his first tournament title this year, advanced to the fourth round when Robin Soderling retired because of illness trailing 6-4, 3-0. Soderling lost the last five games and the final 10 points.

"You're sort of happy you got through to the next round," Federer said. "You're not happy for your opponent, because it's never a way you want to win a match, but you've got to push him to give up."

No. 4 Nikolay Davydenko beat Simone Bolelli of Italy 6-7 (5-7), 7-5, 6-1, and newly engaged No. 6 Andy Roddick converted only two of nine break-point chances but still beat Czech qualifier Ivo Minar 7-6 (7-4), 6-4.

Afterward he confirmed he became engaged to swimsuit model Brooklyn Decker in early March.

"I think I lost half my fan base today," he said.

Julien Benneteau ousted Australian Open finalist Jo-Wilfried Tsonga 6-3, 6-3 in an all-French encounter, and Janko Tipsarevic of Serbia reached the fourth round of a Masters event for the first time, at the expense of Thomas Johansson of Sweden 6-4, 6-4.
