Andre Agassi swept into the fourth round at Wimbledon with a devastating win over Nicolas Massu on Saturday.

In a match that lasted just 81 minutes, the former champion reached the last 16 after dropping just five games.

The second seed dominated throughout against the unseeded Chilean, who had come through an arduous five-setter in the previous round.

Afterwards Agassi said it was nice to feel he had done everything right.

"I felt good about pretty much eveything."

Agassi, semi-finalist last year and runner-up the year before, has yet to drop a set in the three matches in the championship so far.

But he said the second week be far more testing.

"It's almost a different tournament in the second week," he said.

"The grass plays differently and the level of players left in the competition is higher.

"You're playing the best in the world for the biggest title in the world and it's all on the line. I'm looking forward to it."

After claiming the opening set, conceding three games, Agassi romped to victory dropping two games in the remaining sets leaving Massu looking stunned.

The American clinched a fourth round place with an ace on his second match point.

Agassi will next play either Germany's Nicolas Kiefer or Russia's Andrei Stoliarov.
