BOSTON — Jayson Tatum had 37 points and 13 rebounds and Jaylen Brown scored 31 points on Wednesday night to help the NBA-best Boston Celtics bounce back from a rare loss and beat the Dallas Mavericks, 125-112.

The Celtics, who have a league-leading 14 wins, had won nine straight before losing to the Bulls on Monday.

Luka Doncic scored 42 points for the Mavericks, who had beaten Boston four straight times. Three of the wins came on a 3-pointer in the final seconds, and two of those were with no time on the clock.

But Doncic wasn’t able to keep this one close.

The Celtics led by as many as 27 points in the third quarter before Dallas scored 13 of the next 15 points. The Mavericks got within nine points, 104-95 with about 3:30 remaining, and it was 117-107 when it became a game of one-on-one.

And Tatum bested Doncic each time.

Tatum drove for a two-handed, rim-hanging slam, then Doncic was called for an offensive foul. Doncic fouled Tatum, who hit two free throws to give Boston a 121-107 lead, then Tatum blocked Doncic’s layup attempt.

Brown hit a 3-pointer to make it 124-107.

Spencer Dinwiddie, who was listed is questionable because of a dislocated shoulder, had 15 points for Dallas.

Boston led 17-14 six minutes into the game before scoring nine straight points – seven of them by Brown. Tatum scored 16 points with five rebounds in the second quarter, when the Celtics led by 13 points, 55-42, before scoring 13 of the next 14 points to open a 25-point lead.
