Andre Agassi beat Greg Rusedski, 6-4, 6-4, in the semifinals of the Masters Series event in Montreal last night, setting up a championship matchup with French Open winner Rafael Nadal.

The top-seeded Nadal advanced to his first meeting with Agassi by beating unseeded Paul-Henri Mathieu, 6-4, 7-5.

With Nadal serving for the match, Mathieu won four straight points to hand the Spaniard his first loss in 52 service games of the tournament and tie the set at 5. Mathieu handed it back the next game, double-faulting on game point, and Nadal served out for his 64th match win of the season.

Earlier in the day, the fourth-seeded Agassi defeated sixth-seeded Gaston Gaudio of Argentina, 6-3, 6-4, in the completion of a quarterfinal that was postponed Friday night by rain.

Rusedski, of Britain, needed just 67 minutes to beat Dominik Hrbaty of Slovakia, 6-3, 6-4, in their postponed match. . . .

* BOXING: WBC interim heavyweight champion Hasim Rahman unanimously outpointed friend Monte Barrett in Chicago to keep his place at the front of the line to face Vitali Klitschko.

But the fighters did not endear themselves to the crowd of 15,101 at United Center. It was a slow-paced bout, and the fans made it known they were not happy.

Rahman (41-5, 33 knockouts) had said he wanted an early knockout, but was unable to catch Barrett (31-4, 17 KOs).

"I got dinged a little," Rahman said. "Monte is a good puncher. I don't think Klitschko will move around that much, but I showed tonight that I'm ready for 12 rounds."
