LAS VEGAS (AP) _ Andre Agassi moved into the quarterfinals of the Luxor Las Vegas-USTA Men's Challenger tournament Thursday, but not without a fight from Roberto Jabali of Brazil.

Unlike Tuesday, when Agassi appeared to be paired with a minor leaguer in the first round of the tournament being played at the Fetitta Tennis Complex at UNLV, Agassi's second-round opponent forced him to raise the level of his game. Agassi finally prevailed 6-4, 6-1.

While Jabali didn't fare any better than Australia's Michael Tebbutt and the match didn't stretch beyond an hour, he gave Agassi a bit of a scare _ something Tebbutt failed to deliver in his 6-2, 6-4 loss to Agassi two days earlier.

``Yeah, in the first three games (Jabali) hit more balls than Tebbutt did in that entire match,'' Agassi said. ``He's steady and he's not going to make a lot of errors. I had to find my range and it took me a few games to do it.''

Agassi trailed 4-2 in the opening set before he found the range with his penetrating groundstrokes. Agassi, ranked 141st in the world, captured four consecutive games to win the first set. After Jabali held to begin the second set, Agassi ripped through the next six games to close out the match.

In Friday's quarterfinals, Agassi will play Brian MacPhie of San Jose, Calif., a 2-6, 6-2, 6-4 winner Thursday over fourth-seeded Steve Campbell of Detroit.
