MIAMI - Shaquille O'Neal helped the Miami Heat build a 22-point lead. And when they blew it, he delivered the go-ahead dunk in the final minute to beat the Detroit Pistons.
O'Neal had 31 points and 15 rebounds, both season highs, and the Heat earned their most impressive win yet since losing Dwyane Wade, edging Detroit 85-82 Friday night.
The Pistons rallied from a 50-28 deficit to take their first lead with 3:14 left. But O'Neal's dunk with 36 seconds to go put the Heat ahead to stay, 82-80.
Detroit missed three 3-point tries in the final 20 seconds that would have tied the game, including one by Chauncey Billups, who finished 2-for-14 from the field.
Antoine Walker scored 22 points for Miami. Tayshaun Prince had 22 and Richard Hamilton 20 for the Pistons, who failed to overcome a season-low 31 points in the first half.
The Heat improved to 3-2 since Wade was sidelined with a dislocated left shoulder. Detroit's Rasheed Wallace missed the game with a sprained left foot.
