The bizarre match even included a bathroom controversy. In the final set Williams requested a break leading 3-2, but chair umpire Kader Nouni told her to wait until Hantuchova served.

"I've been drinking a lot of liquids, so I have to use the bathroom," Williams told Nouni. "I can't go on a changeover? It won't take me long. I have to use the bathroom. I can't use the bathroom?"

Williams never did take a break.

Venus will next go against 2004 champion Maria Sharapova, one of only two players to win Saturday in the rain-plagued tournament. Venus trailed 4-1 in the second set when her match was halted, and when it resumed two days later she struggled from the start, losing the first seven points.

"If Venus moves up to the ball and takes it off the bounce instead of waiting behind the baseline, she'll be the only one here, including Sharapova," said Williams' father and coach, Richard. "She's not going to beat anyone if she's not moving into the ball."

Venus saw her match as a positive.

"When it was time, I did what it took. I definitely would like to do what it takes earlier," she said. "But I think on the other hand, that kind of competition is invaluable in this kind of tournament. So either way it's good for me."

Henin needed only 56 minutes to beat the No. 15-seeded Schnyder. Henin has lost 15 games in four rounds.

"I did my job perfectly until now," she said.

In the completion of third-round matches suspended Saturday, No. 5-seeded Svetlana Kuznetsova beat Agnieszka Radwanska 6-2, 6-3; No. 6 Ana Ivanovic defeated Aravane Rezai 6-3, 6-2; No. 11 Nadia Petrova swept Virginia Ruano Pascual 6-3, 7-6 (3); and No. 14 Nicole Vaidisova downed Victoria Azarenka 6-4, 6-2.

No. 12 Elena Dementieva lost to 16-year-old Tamira Paszek of Austria 3-6, 6-2, 6-3. Paszek, the runner-up in juniors at Wimbledon in 2005, was thrilled to pull off an upset in her favorite Grand Slam event.

"The strawberries with cream, playing all in white, the grass courts, covering, uncovering the courts, rain delays, rain delays — just everything is so special," the teen said.

Rain has caused an interruption on six of the first seven days of the tournament.

In men's third-round play, 2006 runner-up Rafael Nadal was one point from victory when he hit a cross-court forehand barely wide. His match with Robin Soderling was immediately halted by rain with the score 7-all in the third-set tiebreaker.

Play resumed but then was stopped for the night with Nadal leading 6-4, 6-4, 6-7 (7), 4-6, 2-0.

No. 7 Tomas Berdych beat Lee Hyung-taik 6-4, 7-6 (2), 7-6 (3). No. 10 Marcos Baghdatis defeated No. 23 David Nalbandian 6-2, 7-5, 6-0.
