BOSTON -- Brandon Bass scored five straight points in overtime, helping the Boston Celtics pull out a 100-94 win over the Washington Wizards on the back end of a home-and-home Wednesday night.
Kevin Garnett led the Celtics with 20 points and 13 rebounds, Rajon Rondo had 18 points and 14 assists and reserve Jason Terry had 16 points. Bass finished with 11.
Bradley Beal, Kevin Seraphin and Martell Webster each scored 16 points for the Wizards (0-3).
Bass hit a tiebreaking free throw, making it 93-92, then scored on a twisting layup on the next possession. He added a breakaway dunk with 37.7 seconds left to help seal it.
Boston (2-2) beat the Wizards 89-86 in Washington on Saturday night.
Reserve Chris Singleton's clean drive down the lane for a dunk tied the game with 9.4 seconds left. Rondo then missed a jumper as the horn sounded, sending the game to OT.
Beal's 3-pointer from the top of the key had given the Wizards an 83-82 lead with 68 seconds left, and they made it 84-82 when Webster hit a free throw after Garnett was whistled for a technical.
But Garnett was fouled on Boston's ensuing possession and hit both free throws, tying it. Pierce then stole the ball from Seraphin at midcourt and was fouled, hitting the first of two to push Boston ahead 85-84.
After Webster turned the ball over trying to drive the lane, Rondo hit one of two free throws to make it 86-84 with 27 seconds left.
Singleton nailed two free throws tying it at 86 before Rondo hit a 20-foot jumper from the top of the key to push Boston back in front.
Boston had taken a 71-60 lead with just over 10 minutes to play on Paul Pierce's three-point play, coming on just his second basket of the game, when he was fouled on a fast-break layup. The Wizards then climbed back mostly behind the play of Singleton, who scored six of Washington's eight points as it narrowed the gap to 77-76 on Webster's 3 with 5:19 left.
After Terry nailed a 3 for Boston, the Wizards scored the next four points, tying it 80-all on Seraphin's dunk with 3 1/2 minutes to play.
The Celtics had trailed by seven in a first half that mostly featured poor shooting and sluggish play -- except when Garnett was on the floor -- but scored the initial five points after the break to tie the game at 42.
Garnett had 10 rebounds, two blocked shots and seven points in the first half and the Celtics outscored the Wizards by 11 when he was on the floor.
Washington pulled to a 49-44 lead midway into the third quarter on Beal's three-point play before Boston closed the quarter by scoring 12 of the final 14 points to grab a 66-58 lead entering the final quarter. Chris Wilcox, still working back into shape after heart surgery last season, sparked the run with six points and Terry had a pair of baskets.
Washington shot just 29 percent in the opening quarter and trailed 21-16 at the break, but used a 20-7 run midway into the second en route to a 42-37 halftime edge.
