Greg Monroe had 22 points and nine rebounds to lead Detroit to a 111-109 overtime victory over the Chicago Bulls on Tuesday night in Stan Van Gundy's preseason debut as Pistons coach.
Kentavious Caldwell-Pope added 18 points for Detroit, while Brandon Jennings had 10 points and 10 assists.
Aaron Brooks and Jimmy Butler scored 18 points each for the Bulls, who didn't have Joakim Noah and only played Derrick Rose for 14 minutes.
Brooks scored eight points to pull Chicago to 99-97 in the final 30 seconds of regulation. Monroe's putback gave Detroit a two-possession lead.
Brooks hit three free throws, giving him 15 points in the quarter, and Kyle Singler made 1 of 2 from the line. Caldwell-Pope then fouled Tony Snell with 1.2 seconds left, and he sent the game to overtime.
Jonas Jerebko' 3-pointer gave the Pistons another four-point lead late in overtime.
