Mark Aguirre banked in a three-point shot from the corner with one second left last night to give the Mavericks a 118-117 come-from-behind victory over the NBA champion Lakers. It was Dallas' first victory over Los Angeles in Reunion Arena.

"I really didn't want to take that last one from the side but I couldn't get the ball in the key," Aguirre said. "I just went to the corner, put the ball up and prayed it would go in."

Playing before a sellout crowd of 17,134, the Mavericks overcame a 16-point deficit. It was only their second victory in 11 games with the Lakers.

Back-to-back flying dunks by rookie James Worthy, who had 21 points, put Los Angeles ahead, 116-112. But Aguirre, who finished with 19 points, made a three-pointer to bring Dallas within a point with 10 seconds to go. Michael Cooper then made one of two free throws, after which came Aguirre's game winner.

Worthy missed a shot at the buzzer.

Rolando Blackman, who had a game high 24 points for Dallas, scored 12 of his points in the third period.

Center Pat Cummings, who had 16 rebounds, scored 20 points for the Mavericks in a substitute role. In all, the Mavericks outrebounded the Lakers, 53-32.

The leading scorer for the Lakers was Kareem Abdul-Jabbar with 22.
