Bulls forward Carlos Boozer added 12 rebounds to his team-high 27 points while center Joakim Noah also pitched in 12 boards. Chicago dominated Miami on the glass, particularly on the offensive end, where the Bulls pulled down 19 rebounds compared to the Heat's four.
LeBron James finished with 30 points and six rebounds in the losing effort.
Elsewhere in the Southeast division, the second-place Atlanta Hawks were unable to overcome a lackluster first half in an 85-84 loss to the Detroit Pistons. Atlanta found itself down at halftime, 51-36, and couldn't quite dig completely out of the hole despite outscoring Detroit by 11 points in the final quarter.
