The loss was Boston's first at home this season having won their first 12 home games.

The Pistons held off a late Boston rally and won the game when Billups converted his free throws after being fouled by Tony Allen.

"It was playoff-intense, pretty aggressive out there," Detroit coach Flip Saunders told reporters. "I would say, by far, it was the most aggressive game this season, with all five guys going against each other.

"It got a little bit chippy, so it was a little bit of a playoff-like atmosphere."

Detroit led 85-79 with 3:34 to play but Eddie House and Ray Allen hit three-pointers to tie the game. The score was level until the final seconds, when Paul Pierce missed a fadeaway that would have given the Celtics the lead.

Rasheed Wallace grabbed the rebound and called a timeout with 1.7 seconds left. On the inbound, Allen fouled Billups, leading to the winning free throws.

Billups had a game-high 28 points, including 12 in the fourth quarter, and added eight assists. Richard Hamilton added 21 points and Wallace nine points and 13 rebounds for the Pistons.

Kevin Garnett led Boston with 26 points and 12 rebounds and Ray Allen added 24 points. Despite being the losing team, Boston had 49 percent possession to Detroit's 40 percent.

"It's a good lesson for our guys," Boston coach Doc Rivers said.
