Pistons ran out of gas at the end against the Celtics

Celtics erase an eight-point, fourth-quarter deficit and beat the Detroit Pistons 86-82 on Wednesday night.

Paul Pierce scored 22 points and Ray Allen hit a jumper with 25 seconds left to give the Celtics their first lead of the second half. Shaquille O’Neal had 12 points and 12 rebounds, and Garnett added 11 points and six boards in his second game back after missing nine with a leg injury.

Allen finished with a season-low seven points on 2-for-8 shooting, missing all four of his 3-point attempts. But the Celtics called a play for him out of a timeout and he caught the pass off a screen, turned and (with his foot on the 3-point line) hit the open jumper.

Rodney Stuckey scored 15 points and Greg Monroe had 13 points and nine rebounds for the Pistons, who led by eight with 8 minutes left but did not score over the game’s last 2:43.

The Pistons had won three in a row after coach John Kuester shook up his lineup, benching Richard Hamilton and inserting Monroe at center and McGrady at point guard. It was the longest winning streak of the season for Detroit, which opened with an 11-26 record.

The Pistons led by eight on Ben Gordon’s 3-pointer, but the Celtics made three straight baskets before Chris Wilcox hit one free throw to make it 76-73 with 5:23 left. Rajon Rondo took a jumper near the top of the key, and O’Neal tipped the rebound off the backboard before grabbing it and laying it in; McGrady swiped at him, and the free throw made it 76-all.

It was a two-point game with 3:02 left when O’Neal missed two free throws, and Detroit made it 82-78 on Monroe’s reverse layup. But Garnett scored inside, and then Pierce made a jumper in the lane.

After McGrady missed, Garnett missed a long jumper but Rondo got the rebound and called timeout. The Celtics ran Allen off a screen to get him open near the 3-point line on the right side and he sank the basket; it was initially ruled a 3-pointer, but replays showed his right foot was on the line, making the score 84-82.

Stuckey missed a leaner in the lane, and Garnett grabbed the rebound, then hit one of two foul shots. Gordon drove and missed a layup over Glen Davis’ outstretched arms.
