BOSTON -- Instant reaction after the Los Angeles Lakers posted an 90-89 triumph over the Boston Celtics Sunday at TD Garden:

How the game was won: Kobe Bryant and Andrew Bynum led four Lakers in double figures with 19 points apiece as Los Angeles rallied after giving up a double-digit lead. Celtics guard Rajon Rondo paced Boston with 21 points and 12 assists.

Turning point: With the Celtics clinging to a one-point lead, Ron Artest drew an offensive foul on Paul Pierce, who was whistled for pushing off driving to the basket. At the other end, Ray Allen blanketed Bryant, but he managed to uncork a fadeaway from the free-throw line for a 90-89 advantage with 7.3 seconds to go. Earlier, Rondo sparked the Celtics on a 15-0 run to turn a six-point deficit into a 49-40 advantage with three minutes to play in the first half, but Boston couldn't maintain the lead.

Unsung hero: One night after finishing 6-of-18 for 18 points against Atlanta, Boston's bench rebounded to go 11-of-20 for 28 points, but it wasn't enough. Boston shortened its rotation, using just Eddie House, Tony Allen, Glen Davis and Rasheed Wallace. With Boston trailing by 11 after the first quarter, Tony Allen provided a monster spark off the bench. Allen finished 6-of-9 shooting for 14 points and boasted a plus-6 in the plus/minus. Davis ended with a plus-12, just one game after a minus-19 against Atlanta.

State of the Game: Eighteen Boston turnovers led to 23 points for the Lakers. Five of those turnovers came in the fourth quarter as the Celtics fumbled away the game.

What it means: The Celtics, desperate for a win after dropping 10 of 16, including both ends of a Thursday-Friday back-to-back against Orlando and Atlanta, suffered another tough-to-swallow loss in yet another winnable game. Boston isn't out of the woods, yet, either. The team departed after Sunday's game for Washington, D.C., where Monday night they close out this hellacious stretch against the Wizards.
