Celtics cool off Heat in Miami

Gordon Hayward had 29 points and nine rebounds, Jaylen Brown scored 25 points and the Boston Celtics led virtually the entire way to beat the Miami Heat 109-101 on Tuesday night.

Kemba Walker added 16 points and eight assists for Boston, which got 11 points from Marcus Smart and a 10-point, 11-rebound effort from Daniel Theis.

Goran Dragic led Miami with 23 points and Jimmy Butler scored 20. Bam Adebayo had 16 points and 10 rebounds and Duncan Robinson scored 12 points for the Heat _ who lost at home to an Eastern Conference opponent for the first time in 14 games this season.

Boston outscored Miami 15-0 from 3-point range in the game's first nine minutes, a big reason why the Celtics took control from the outset and built as much as a 13-point lead in the opening quarter.

But the Heat never held the lead in the second half. Every time they got close, Boston had the answer and Smart's 3-pointer with 1:50 left put Boston up by eight to all but seal matters.
