Kirk Hinrich scored 29 points, Luol Deng added 22 and the Ben Wallace-less Bulls beat the listless Pistons 106-88.

"It is significant because we are trying to move up," Bulls coach Scott Skiles said.

Detroit's magic number is four to clinch home-court advantage in the Eastern Conference playoffs over Cleveland, which plays at Detroit on Sunday, with seven games left for both teams.

But the Cavaliers are ahead of Chicago by just a half-game in the Central Division.

Wallace missed the game against his former team after going to the hospital with sinus inflammation, and his absence seemed to deflate a crowd fired up to jeer him again.

"The game wasn't as emotional not playing against him, and not as much fun," Billups said.
