AUBURN HILLS, Mich. (AP) - Josh Smith made a 3-pointer as time expired and finished with 20 points to lift the Detroit Pistons to a 99-98 victory over the Minnesota Timberwolves on Thursday night in both teams' exhibition finale. J.J. Barea's layup with 3.6 seconds left gave the Timberwolves a 98-96 lead but Smith, who got the ball out of a timeout, launched his shot in the final second. It hit the rim and fell in as the horn sounded. Greg Monroe and Will Bynum each added 17 points, rookie Kentavious Caldwell-Pope scored 13 and Andre Drummond grabbed 20 rebounds for the Pistons. Kevin Love had 19 points and 10 rebounds, and Kevin Martin added 18 points for Minnesota on a night both coaches gave their younger players plenty of playing time.
