ESPN: Roddick sharp in straight-sets rout, Blake moves on

With much of the attention focused on triple champion Roger Federer and his chief rival, Rafael Nadal, Roddick has rolled through his first three matches losing just one set.

His Davis Cup teammate, No. 6 James Blake, beat Stefan Koubek 6-4, 3-6, 7-6 (5), 6-1 in a match that finished after 1 a.m. Sunday.

Roddick, the 2003 champion, blasted 19 aces and had 41 winners in the 84-minute match in Arthur Ashe Stadium.

“It felt good,” Roddick said. “I wanted to go out and hit the ball and be aggressive, get hold of my forehand, if I could. I felt like I did that today.”

The victory sets up a fourth-round match against ninth-seeded Tomas Berdych.

“We play kind of similar,” said Roddick, who has a 1-1 record against the Czech. “We both serve big and hit a pretty big ball from the baseline.

“If that’s the case, it’s going to come down to a couple points here and there, who converts their chances on the other guy’s serve.”

In other matches, Federer was too much for 6-foot-9 rookie John Isner in a 6-7 (4), 6-2, 6-4, 6-2 victory.

Isner used his booming serve to win the first-set tiebreaker, and several fans barked for their favorite Georgia Bulldog. Federer quickly figured it out and kept up his bid for a fourth straight Open title.

“I started to pick up on his serve for the second set,” Federer said.
