ROGER THAT

WIMBLEDON, England - Second-seeded Jelena Jankovic was ousted in straight sets in the fourth round by Tamarine Tanasugarn today, leaving the women's draw without its top three ranked players.

Jankovic's 6-3, 6-2 loss means that none of the top three women reached the quarterfinals - the first time that's happened at a Grand Slam tournament in the Open era. No. 1 Ana Ivanovic and No. 3 Maria Sharapova were upset last week.

The Williams sisters, meanwhile, moved closer to another Wimbledon final. Defending champion Venus Williams beat Russian teenager Alisa Kleybanova 6-3, 6-4, while two-time winner Serena downed Bethanie Mattek - the only other American left in the men's or women's draw - 6-3, 6-3.

In men's play, five-time champion Roger Federer swept Lleyton Hewitt - the last man to win the title before him - 7-6 (7), 6-2, 6-4 to extend his winning streak on grass to 63 matches and 38 in a row at the All England Club. Federer, who served 21 aces, has now beaten his Australian rival in 12 consecutive matches.

Playing with her left knee heavily strapped, Jankovic was never in serious contention against the 60th-ranked Tanasugarn. The 31-year-old Thai, playing in her 12th consecutive Wimbledon, also was treated for a lower back problem during changeovers in the second set.

After converting on match point to reach the quarterfinals of a Grand Slam for the first time, Tanasugarn covered her face with her hands and broke into tears.

Jankovic said she played with a tear in her knee sustained during her third-round win Friday over Caroline Wozniacki.

"I was always a step behind," said the Serb, who committed 19 unforced errors. "It was very hard for me. I tried the best I could and she was quite solid and didn't make any mistakes. I wasn't moving the way I usually move. I just couldn't play at my best."

Venus Williams, a four-time Wimbledon winner, nearly squandered a 5-1 lead in the second set against the 18-year-old Kleybanova. She lost nine points in a row from her third match point in the eighth game and saved three break points at 5-4 before finally closing it with a backhand volley winner.

Serena Williams wobbled slightly after going up 3-0 in the second set as Mattek raised her game by playing serve-and-volley. Williams received a warning for an audible obscenity in the fifth game, but that didn't stop her as she won the next five points. She finished the match with a backhand drop volley into the open court.

The Williams sisters, who have not dropped a set in their four matches, played back-to-back on Court 2 - nicknamed the "Graveyard of Champions' for its long history of upsets. They were also scheduled to play doubles together on Court 2 later today.

Venus Williams, who will face Tanasugarn in the quarters, was clearly not happy with the court scheduling.

"There's not too much I'm going to say about that in the press," she said. "I think that no matter where we play we realize we have to play well. That's pretty much all I have to say."

Between them, Venus and Serena have won six of the last eight women's singles titles at Wimbledon. They're in opposite halves of the draw and could meet in the final Saturday. The Williams sisters faced each other in the 2002 and ‘03 finals, with Serena winning both.
