The Boston Celtics played like a championship-caliber team for the final 12 minutes last night, and that was enough against the up-and-coming Indiana Pacers.

Indiana led for all but a few minutes in the first three quarters, but visiting Boston outscored the Pacers 29-16 in the fourth while holding them to 26 percent shooting for a 95-83 victory.

"We just kept playing defense," Celtics coach Doc Rivers said. "Then all of a sudden, our shots started falling and our defense stayed."

Paul Pierce scored 21 points, Ray Allen added 17 and Kevin Garnett had 11 points and 13 rebounds.

Boston point guard Rajon Rondo missed his fifth straight game with a sprained left ankle. The Celtics improved to 4-1 without him and maintained the best record in the Eastern Conference. The Celtics were coming off an 86-78 loss at Orlando on Christmas that ended a 14-game winning streak.

"You always want to get back on track, especially after a tough loss," Pierce said. "All of these road games are tough, no matter who you're playing because teams are comfortable in their home environment."

Glen Davis scored 14 points and former Pacer Marquis Daniels added 12 for the Celtics. They combined for eight points and two assists during the 13-2 run to start the fourth quarter that put the Celtics in control for good.

Daniels entered the game with his Celtics trailing 60-53 in the third quarter. The 6-6 guard used his height advantage against Indiana's 6-footers Darren Collison and T.J. Ford.

"The game turned around when they went to a big 1 guard and were able to post up T.J. and Darren," Pacers coach Jim O'Brien said. "That slowed the tempo and got them back in the game."
