CINCINNATI -- Andy Roddick, coming off a runner-up finish last week, beat Wayne Ferreira 6-3, 6-2 Thursday night to advance to the quarterfinals of the $2.95 million Cincinnati Masters Series.

It was the 47th match victory this year -- tops on the ATP tour -- for Roddick, who lost to Guillermo Canas in the finals of the Masters Series event in Toronto.

``I played solid throughout, maybe one sloppy game,'' Roddick, 19, said. ``My serve was working, and I made very few mistakes.''

Match point was a 132-mph ace down the center line.

``I feel really focused,'' the 12th-seeded Roddick said. ``I'm relaxed and I'm having a really good time.''

Roddick will play Fernando Gonzalez on Friday in the quarterfinals. Gonzalez beat Richard Krajicek 6-2, 3-6, 6-3.

A resurgent Andre Agassi also advanced with a 6-4, 7-5 victory over Thomas Enqvist.

He will face top-seeded Lleyton Hewitt (7 p.m. ET, Fri., ESPN2), who beat 35th-ranked Jarkko Nieminen 2-6, 6-2, 6-3, in the quarterfinals.

``It was a high-standard match,'' said Agassi, who had been only 2-4 against Enqvist but wore him down with unrelenting baseline strokes. ``It was quite a thriller.''

Agassi, the No. 6 seed, has won four titles this year, including one in Los Angeles two weeks ago. He skipped the tournament in Toronto.

``I feel pretty good about the year,'' said Agassi, who is 37-5 in matches this year. ``Unfortunately, the Slams haven't worked out very well.''

Agassi missed the Australian Open with a wrist injury, lost in the quarterfinals of the French Open and lost in the second round at Wimbledon, his last tournament before Los Angeles.

Otherwise, he has had a remarkably consistent year, reaching at least the quarterfinals in eight of 10 appearances.

Hewitt, the U.S. Open and Wimbledon champion, breezed to a 6-0, 6-0 win in the first round, and led 5-0 when his second-round opponent retired with a toe injury.

``I'm glad I had a good workout out there today,'' Hewitt said. ``That's what you want in these tournaments going into the Grand Slams.''

The U.S. Open begins Aug. 26 in New York.

``That's obviously the big one,'' Hewitt said. ``I want to be hitting the ball and peaking for that.''

In other matches, eighth-seeded Juan Carlos Ferrero beat Taylor Dent 6-7 (5), 6-1, 7-6 (4), and No. 16 Carlos Moya defeated fellow former French Open champion Michael Chang 6-4, 6-3.

``I had some chances early on in the first set, but I wasn't quite able to capitalize on them,'' Chang said. ``He played some smart tennis. There were a few points here and there that could have made a difference.''

In the quarterfinals, Moya will play Rainer Schuettler, who eliminated Xavier Malisse 6-4, 6-3. Ferrero will play Wayne Arthurs, who beat Tommy Robredo 7-6 (3), 4-6, 6-4.
