Pierce and Davis have become one of the Eastern Conference's better scoring duos, combining to average more than 45 points, 12 rebounds and nine assists per game.

"We played great," said Davis, who shot 7-of-16 from the floor. "I think we executed what we needed to execute. I think we moved the ball, one more pass, and that's how we need to win games, continue to move the ball and hit the open guy."

Behind Davis and Pierce, the Celtics built a 62-51 halftime lead. But the Warriors battled back and took a 77-76 lead with 2:27 remaining in the third quarter on Derek Fisher's 3-pointer.

"We're giving up too many points to start the game," said Fisher, who scored 12 points. "We're allowing basically everyone we play to have 30-point first quarters and 60 points for the half, which means that a team is being extremely efficient on the offensive end against us."

The Celtics rebounded to take an 85-80 edge after three quarters, then stretched the advantage to 91-82 early in the fourth on rookie Orien Greene's jumper.

A jumper by Mark Blount with 3:36 remaining gave the Celtics a 103-90 lead.

Boston got a big boost from Marcus Banks, who scored 16 points and helped the club weather recent injuries to two points guards.

Delonte West was sent home before the game with a mild concussion sustained Saturday against Chicago and Dan Dickau is scheduled for surgery Tuesday for his ruptured right Achilles tendon, suffered in the same game.

"The guys stepped up good," Davis said. "Marcus came in, gave us some energy and Orien came in and played good. That's what we need, for guys to step up and just be a key factor and get us in our sets."

Blount scored 17 points and Al Jefferson added 13 and eight rebounds off the bench for the Celtics, who held a commanding 60-30 advantage in points in the paint.

"The difference from this year and last year is that this year I kind of know the respect and I understand the game a lot better," Jefferson said. "I've got a year under my belt and I understand the game. I still have a long way to go."

Troy Murphy had 27 points and 12 rebounds and Baron Davis collected 24 points and nine assists for Golden State, which fell to 1-2 on a five-game road trip. The Warriors made just 5-of-21 3-pointers.

"We just played in spurts," said Baron Davis, who went 8-of-13 from the line. "You can't play in spurts on the road and expect to win. You've gotta battle and we didn't really battle. You have to be as solid as possible when you get the score close on the road and just kind of grind everything out."

Golden State coach Mike Montgomery watched as his club lost consecutive games for just the second time this season.

"You can put it on the defensive end, you can put it on the offensive end," Montgomery said. "Sometimes, the shots that we take on offense lead to having to come back and play (transition) defense. We tend to come down one-on-three and we're right back on defense again and maybe you need to rest on offense, make a few more passes."
