LONDON -- Andy Roddick and Roger Federer yesterday reached the round of 16 at Wimbledon, and defending women's champion Serena Williams breezed past Magui Serna in 58 minutes.
For the third time in the tournament's 127 years, organizers were forced to schedule matches on the middle Sunday -- usually a rest day -- to clear a backlog after washouts Wednesday and Saturday.
Second-seeded Roddick beat fellow American Taylor Dent, 6-3, 7-6 (8-6), 7-6 (7-1). "I played well today, I lifted my game -- I was forced to," Roddick said. He'll meet 6-foot-7-inch Alexander Popp in the next round.
Dent took a 6-3 lead in the second-set tiebreaker when Roddick hit a forehand return wide. Roddick then angrily slammed his racket to the grass, and the outburst apparently helped. He won the next five points and closed out the set with a backhand winner.
In the final tiebreaker, Dent missed four volleys and fell behind, 6-0. Roddick closed out with a service winner, then raised his arms to cheers on Court 1.
The top-ranked Federer hit 44 winners and advanced with a 6-3, 6-4, 6-3 win over Thomas Johansson. Federer rifled a forehand return on match point after 1 hour 37 minutes.
He broke Johansson once in each set and said, "I'm feeling very good, definitely better than last year because I know I already won this tournament, so I know I can do it again."
Federer next plays Ivo Karlovic, who hit 39 aces to beat No. 18 Feliciano Lopez.
Centre Court was full by the time Williams beat Serna, 6-4, 6-0.
The top-seeded Williams looked subdued with both her mother and father watching from the stands, but still had 11 aces and 29 winners with only one double fault and 11 errors.
In an early upset, 30th-seeded American Vincent Spadea knocked off No. 8 Rainer Schuettler, 6-4, 6-2, 6-3. Spadea next plays 12th-seeded Sjeng Schalken, who beat Thomas Enqvist in five sets.
Early on, seventh-seeded Jennifer Capriati beat Nathalie Dechy, 7-5, 6-1, in the first singles match completed in more than 40 hours at Wimbledon.
Also, fourth-seeded Amelie Mauresmo advanced, and Karolina Sprem -- who eliminated Venus Williams -- defeated No. 32 Meghann Shaughnessy, 7-6 (7-5), 7-6 (7-2).
On Court 7, Wayne Ferreira's record 55th consecutive Grand Slam event ended in a 4-6, 6-4, 6-1, 6-4 loss to Florian Mayer, who earlier upset Guillermo Coria.
