Isiah Thomas scored a season-high 32 points and had 16 assists to rally the Detroit Pistons to a 131-114 victory over the Boston Celtics last night. The loss was only the Celtics' second in Boston Garden this season.

Boston built a 108-100 lead early in the fourth quarter and was ahead, 110-106, with six minutes left. Detroit then scored 18 of the next 20 points. Thomas scored six points in the run, including a basket that broke a tie at 112 with three minutes left.

"People say you shouldn't run with the Celtics, but I'm trying to develop a team with a running style," Detroit Coach Scotty Robertson said. "I'm not going to change our system when we play the Celtics. However, I though they looked tired at the end. When you play an overtime game against Atlanta (Saturday night) and then have to travel, it takes something out of you."

Bill Laimbeer, making 10 of 14 shots, scored 21 points for the Pistons and had 16 rebounds. Larry Bird led the Celtics with 20 points, 10 rebounds and six assists. Boston center Robert Parish scored 18 points in his first game since missing a week with a sprained ankle.
