AUBURN HILLS, Mich. (AP) _ Christian Laettner scored 15 points and Jermaine Jackson's steal with 5.9 seconds left clinched the Detroit Pistons' 99-96 exhibition victory over the Minnesota Timberwolves on Friday night.

Grant Hill and Jerry Stackhouse added 14 points each for the Pistons (4-1), whose reserves blew a 22-point lead before coming back for the win.

Rookie Wally Szczerbiak led the Timberwolves (2-4) with 20 points. But Minnesota's No. 1 draft choice cost his team its last chance at victory when, with the Pistons leading 97-96, his pass for William Avery was stolen by Jackson.

Jackson, a rookie free agent from Detroit Mercy whose free throw put the Pistons ahead with 23 seconds left, passed ahead to Mikki Moore for a finishing dunk just before the final buzzer.

Kevin Garnett had 17 points and Terrell Brandon 15 for the Timberwolves, who also got 11 each from Radoslav Nesterovic and Bobby Jackson.

Don Reid and Michael Curry each had 10 points for Detroit.

The Pistons dominated when their starters were in the game, opening their biggest lead of the night, 64-42, on two free throws by Hill with 7:04 remaining in the third quarter. Hill left for good with 3:22 remaining, and Detroit coach Alvin Gentry had all his starters on the bench by the end of the period.

Garnett, limited to eight points through three quarters, took advantage of the Pistons' subs to score nine points in a 19-5 run that put the Timberwolves up 84-83 when he made two free throws with 5:55 left.

A short hook from Nesterovic gave the Timberwolves their last lead, 96-95, with 56 seconds remaining. Curry tied it with a free throw before Jackson put the Pistons ahead for good.
