BOSTON, Jan. 11 (Ticker) -- Antoine Walker's knee may be bothering him, but plenty of his teammates picked up the slack.

Paul Pierce scored 16 points to lead six players in double figures as the Boston Celtics overcame Walker's struggles en route to a 104-90 victory over the Detroit Pistons.

Walker twisted his knee in Wednesday's loss to San Antonio and underwent an MRI on Thursday that did not reveal any major damage.

"When I'm in the game I try not to think about it," he said. "Obviously it's going to stop some of my mobility to a certain degree. I've got to fight through it one more game and I should be starting to feel a lot better come Wednesday."

Walker was questionable until game time but started and managed just five points on 1-of-14 shooting. He collected 11 rebounds and seven assists while the rest of the Celtics did the scoring.

"We haven't been winning so I wanted to definitely play," he said. "Just to be out on the court to make a difference to continue to draw the double-teams and things like that."

"He's still a presence out there, whether he's scoring or not, and he helps our ballclub," Pierce said. "Thankfully, we got this win and won by the margin we won by so we can rest him up."

Erick Strickland scored 14 points and Tony Battie and Vitaly Potapenko added 12 apiece for Boston, which shot 52 percent (41-of-79) and won for just the fourth time in 10 games.

"Every night during the course of a long season you need guys to step up and make big plays," Walker said. "We were able to throw some guys in there change the scheme a little bit and it worked real well tonight."

"It takes the pressure off of us when the guys come in and give a contribution and that's what we need," Pierce said. "We played with a lot of unselfishness tonight. Other guys got the opportunities, took some shots and knocked them down and took advantage of that."

Boston never trailed, pulling away in the second quarter behind the scoring of Pierce and Potapenko. The Celtics had a 27-24 lead less than three minutes into the period before scoring 20 of the next 25 points.

Pierce scored seven points during the burst, including the first three. He began the stretch with a jumper and followed with a technical foul shot.

After a basket by Kenny Andeerson made it 37-27 with 6:40 left, Potapenko finished the run with four consecutive baskets. He capped the spurt with a dunk that gave Boston a 47-29 lead with 3:28 to go.

Walter McCarty scored a season-high 12 points and Anderson finished with 10 for the Celtics, who blew it open in the second half.

"The guys that beat us tonight (weren't) the ones that normally beat you," Detroit guard Jerry Stackhouse said. "If you look at the stats, five or six guys in double figures, we can talk defense all you want until we find a way to score some points and be in the game."

Boston had a 56-42 advantage with 9:43 left in the third period before pulling away. Pierce and Strickland each scored seven points to help the Celtics open their largest lead, 84-55, with 1:56 left.

Stackhouse scored 21 points and Victor Alexander scored all of his season-high 12 in the fourth quarter for Detroit, which has lost 11 straight on the road and 12 of its last 14 overall.

Ben Wallace had 10 points and 11 rebounds as the Pistons shot just 36 percent (31-of-86).

"I obviously didn't like the way we played, although I liked the effort guys gave in the fourth quarter," Detroit coach Rick Carlisle. "I thought we played with great energy and were really unselfish. The energy hasn't been there we're at a critical point and we've got to figure out a way to get it back."
