WIMBLEDON, England - — Ask Venus Williams about playing Jelena Jankovic in the Wimbledon quarterfinals Wednesday. Or ask Jankovic about playing Williams. They'll deliver the standard line about taking things one round at a time.

But on this middle Sunday with all players having a day of rest, it wouldn't be astonishing if both have looked at the draw and seen they are one win from reprising a Wimbledon match that Williams would love to erase from her memory bank.

It was 2006 and Jankovic, then 21 and never having made the second week of a Grand Slam, upset defending champion Williams 7-6 (, 4-6, 6-4 on the fourth match point of a tense third-round match.

But before there can be a rematch of that upset, Jankovic has to get past Tamarine Tanasugarn on Monday, and Williams will have to defeat Alisa Kleybonova.

That victory over Williams has done nothing to convince Jankovic that she has a comfort level on the All England Club lawns.

"Grass is not my favorite surface," she insisted Saturday after surviving a knee injury and horrific opening set to beat 17-year-old Caroline Wozniacki of Denmark 2-6, 6-4, 6-2 and reach the round of 16.

The fourth round is as far as Jankovic has gotten at Wimbledon, with her prodigious ground strokes, great defense and average serve. But, assuming the knee heals, she should reach the quarters.

It was another dry day at Wimbledon as the tournament completed its first week with only a 90-minute rain delay, which came Friday.

On the men's side, Rafael Nadal joined five-time defending champion Roger Federer in the fourth round by defeating Nicolas Kiefer, 7-6 (3), 6-2, 6-3.

Nadal will face Mikhail Youzhny in the fourth round. The two met in the fourth round a year ago at Wimbledon, with Nadal coming back from two sets down to win 6-2 in the fifth. Meanwhile, Federer's next opponent is Lleyton Hewitt, the former Wimbledon winner. Federer holds a 13-7 lifetime edge and has won their past 11 meetings.

Other men's winners: No. 8 Richard Gasquet, No. 12 Andy Murray and four unseeded players: Janko Tipsarevic, Rainer Schuettler, Arnaud Clement and Marin Cilic.

Jankovic, seeded No. 2, No. 7 Williams, Tanasugarn and Kleybanova reached the fourth round along with four others in the lower half of the draw: No. 5 Elena Dementieva, No. 21 Nadia Petrova, Alla Kudryavtseva and Shahar Peer, who upset No.9 seed and French Open runner-up Dinara Safina.

Kudryavtseva, who upset Maria Sharapova earlier in the week, caused some commotion after her victory when she told the media to "get over it" when more questions were asked about her criticism of Sharapova's outfit.

If Williams doesn't want to look ahead, she is even less talkative about the increasing possibility that she and her sister, Serena, could meet in a Grand Slam final for the first time since Wimbledon in 2003, when Serena won. Venus, 28, has won four Wimbledon titles; Serena, 26, has two.

"The more we progress, obviously the closer it gets," Venus said. "But personally, I'm really focused on my next round."

Williams defeated Maria Jose Martinez Sanchez 6-1, 7-5, playing nearly error-free in the opening set and concluding the match with a Wimbledon-record 127 mph serve.

Williams won 12 of the final 14 points. The final serve topped the previous Wimbledon high of 126 achieved by both Venus and Serena Williams. Venus holds the women's tour record with a 129 mph serve at last year's U.S. Open.

Unable to play her usual aggressive game, Jankovic played a lot of deep, safe balls in the final set, trying to coax errors. It worked. Wozniacki, frustrated at her inability to return serve from the deuce court, had 13 unforced errors in the third set to three winners.
