Viewer's guide for Sunday

WIMBLEDON, England -- The third-round matchup between Americans Andy Roddick and Taylor Dent promises to be one of the best of the day as Wimbledon plays on the middle Sunday for only the third time in the history of the All England Club.

Two of the hardest servers in the men's game, Roddick and Dent last met at the Australian Open in January when Roddick dismissed Dent with ease 6-2, 6-0, 6-2. But Roddick is doing his best not to be lulled into a false sense of confidence.

"What's done is done," Roddick said Friday. "He just had a terrible day. He just played horrible and I played well. We had a pretty intense match at Queen's last year, and that's probably what I'll remember a little bit more than Australia."

Dent, 1-2 lifetime against Roddick, got his lone win in 2003 at Memphis 6-1, 6-4. Dent will be faced with the challenge of stopping a player who has won 17 of his last 18 American matches on grass. If Dent succeeds, he will advance to the fourth round, his best Wimbledon showing to date.

Bad weather has made play intermittent or nonexistent the first week. So the day features a plethora of high-profile matches.

Potential show stoppers

  • Roger Federer was the heavy favorite to win Wimbledon coming into the tournament. He has done nothing to change that in his first- and second-round matches. After ousting Alex Bogdanovic in the first round 6-3, 6-3, 6-0, Federer took less than a hour to send qualifier Alejandro Falla packing. Because Federer has yet to play his third-round match, he will have the benefit of being first on Sunday. What kind of challenge does Thomas Johansson pose? Well, Federer has won all five meetings between the two, three in straight sets.

  • Tim Henman continues his quest to be the first British Wimbledon champion since Fred Perry in 1936 with a seemingly favorable third-round matchup against Hicham Arazi. Henman is 8-3 lifetime against Arazi but has lost the last two meetings, both on clay. They have met just once on grass, in 2000, with Henman winning 6-3, 6-3, 6-3. Arazi, making his ninth consecutive appearance at Wimbledon, is looking to break into the final 16 for the first time.

  • Serena Williams is cruising toward a quarterfinal showdown with Jennifer Capriati, but she must first get past her third-round matchup against Spain's Magui Serna. Considering Williams last faced Serna in 1999, winning 6-1, 6-0, it's likely that Serena will roll into the fourth round as she has in four of her five previous Wimbledon appearances (lost in third round, 1998).

  • Jennifer Capriati is doing her part to give the fans of Wimbledon what they want, the aforementioned quarterfinal clash with Serena Williams. Dechy poses little threat, having lost all four meetings with Capriati, including most recently at the 2003 Eastbourne quarterfinal 6-1, 7-5.

  • Amelie Mauresmo finds herself in a good position as the lone top-10 player remaining in her quarter of the draw. She is 2-0 lifetime against her third-round opponent, Ludmila Cervanova, and appears destined for a date with Capriati or Williams in the semifinals.
