Kyrie Irving scored 10 of his season-high 47 points in overtime as the Boston Celtics rallied once again from a double-digit deficit to beat the Dallas Mavericks 110-102 and extend their winning streak to 16 games.
The Mavericks led by as many as 13 points in the fourth quarter, but as they have several times during their winning streak, the Celtics stormed back.

Boston tied the game at 96 when Irving stole the ball from Dirk Nowitzki and fed Jayson Tatum for an alley-oop lay-up that hung on the rim for a full second before dropping through.
Irving scored his team's first six points of overtime. Then after Jaylen Brown gave Boston a 104-102 lead with a jumper with 1:39 to play, Irving went to work on Yogi Ferrell, backing him down and drawing contact on a lay-up with 48.5 seconds to play. Though Irving missed the free throw to keep the score 106-102, Dallas never got closer.
Harrison Barnes scored 31 points and Wesley Matthews had 18 for Dallas, which came back from an early double-digit deficit as the Celtics went cold for much of the second and third quarters.
Irving and Barnes had chances in the final 30 seconds but both missed shots that would have given their teams the lead.
The Mavericks fell behind by as many as 15 points in the first half, outscoring the Celtics 55-35 over the second and third quarters.
