Pete Sampras dominated Andre Agassi when it counted the most yesterday.

In a rematch of their Wimbledon final four weeks earlier, Sampras needed a pair of tiebreakers to beat Agassi, 7-6 (7-3), 7-6 (7-1), for the championship of the Mercedes-Benz Cup in Los Angeles.

The match was as tight as could be, except for the tiebreakers, where Sampras won 14 of the 18 points contested.

Otherwise, Agassi won 74 points to 68 for Sampras.

"Two tiebreakers," Sampras said with a smile when asked the difference in the 1-hour 35-minute match. "Andre is so tough for me to play. He returns so well."

But not in the tiebreakers, where Sampras's service was invincible. He served five winners in the first-set tiebreaker, with one ace and three serves Agassi couldn't return. Agassi opened the second-set tiebreaker with a double fault--his only one of the match. Sampras followed with an ace, and it was all downhill from there. Agassi won a point on his serve to make it 3-1 before Sampras won four straight points to close out the match.
