But Avery Bradley drew an offensive foul on Los Angeles' Jamal Crawford with 26 seconds to go, and Pierce held on to the ball before making a 3-pointer with 2.5 seconds left to clinch the win. Jeff Green and Leandro Barbosa scored 14 points each for the Celtics.
The Clippers were led by Bledsoe, replacing Paul, and Crawford, who made a 3-pointer at the buzzer, with 23 points each.

That gave the Lakers a 98-95 lead, and they held on despite missing four free throws in the final 16.8 seconds. Bryant scored 18 points for the Lakers, who have won five of six, including their last two games without Dwight Howard.
