BOSTON (AP):

CARON BUTLER scored 21 and Washington beat Boston 88-83 on Monday night for the Wizards' second victory over the Celtics in three days.

Antawn Jamison added 20 points and 10 rebounds for the Wizards, who handed Boston their first two-game losing streak of the season. Butler scored nine points during a 25-6 run over the final 6:24 of the fourth quarter to give the Wizards their fifth win in the last six games against Boston.

Boston also lost consecutive games at home for the first time all season and dropped to 30-6. The Celtics are 2-3 over their last five and have averaged 85 points a game over that span.

Eddie House scored his only five points of the game to give the Celtics their largest lead at 77-63 with 6:24 remaining before the Wizards rallied.

Trailing by 14, the Wizards went on a 19-4 run to take an 82-81 lead with 40.1 seconds remaining, capped off by Butler's three-point play.

Kevin Garnett failed on a three-pointer, but Paul Pierce was fouled on the rebound and sank both free throws to regain the lead for Boston at 83-82. Butler then responded with a high-arcing lay-up as he beat Pierce off the dribble with 19.6 seconds remaining. Garnett failed on another chance to regain the lead for Boston when his turnaround jumper clanked off the back rim. Butler got the rebound and hit a pair of free throws for an 86-83 lead with 8.3 seconds remaining.

Garnett led the Celtics with 23 points and Pierce added 18.

Lakers 123, Sonics 121

In Seattle, the Lakers surged to the top of the Pacific Division with an overtime victory and are on their longest winning streak since 2004.

Kobe Bryant scored 48 points and capped his season-best offensive outburst by swishing an 18-footer with 4.3 seconds left in overtime to help the Lakers win their seventh straight game.

The Lakers were playing their first contest without injured centre Andrew Bynum, who will miss at least eight weeks after suffering a left knee injury in Sunday night's win over Memphis.
