Celtics use big second half to beat Sixers

Boston closed out the third with a 10-2 run over the final 3 minutes and outscored the Sixers 28-16 in the period. The Celtics also scored 16 of the first 22 points in the fourth quarter — seven from Rondo — to put away the game.

The Celtics acquired Bass in December in a trade with Orlando for Glen "Big Baby" Davis, and he worked his way into the starting lineup after the All-Star break. Although he solidified the power forward position after Garnett moved to center, he hadn't done anything spectacular — until Monday.

Bass hadn't scored more than 22 points in a game this season and he matched his regular-season career high of 27 on Monday night. His playoff high was 19 points, in 2008.

He left the game to a standing ovation with 2 minutes left and the Celtics leading by 18.

Boston tied it 57-all when Bass stole the ball from Thaddeus Young and got to the free throw line, making both foul shots. After a Sixers miss, Rondo found Bass underneath for the dunk. Bass added another crowd-pleasing dunk before knocking loose a ball to start Rondo on a fast break he finished by finding Allen for the layup.

Notes: Actor Will Smith, a 76ers co-owner, was at the game, as were comedians Chris Rock and David Spade. ... Bradley did not play because of problems in both shoulders, coach Doc Rivers said. ... Rondo had seven assists in the third quarter. He picked up one of his most spectacular when he slipped at the free throw line but left-handed the ball to Greg Stiemsma for the dunk.
