Heat clamp down in OT to hold off Mavs

Jimmy Butler scored a game-high 33 points and added nine rebounds and six assists as the host Miami Heat defeated the Dallas Mavericks 123-118 in overtime on Sunday night.

Mavericks star Kyrie Irving had 27 points and six assists, while P.J. Washington added 21 points and 10 rebounds. Naji Marshall had 19 of his 20 points after the first half and Dereck Lively II had 14 points, 13 rebounds, four assists and two blocks.

Klay Thompson, who went 0-for-8 from the floor in Dallas' 123-120 win at Denver on Friday, bounced back with 15 points on 5-for-12 shooting.

The Mavericks played without reigning NBA scoring champ Luka Doncic (wrist).

Miami, which had been off since Monday, had double-doubles from Bam Adebayo (19 points, 11 rebounds) and Tyler Herro (18 points, 10 boards).

The Heat went ahead for good on Adebayo's 3-pointer that made it 120-118 with 2:54 left in overtime. Dallas missed its final seven shots after Lively's dunk put the Mavericks up 118-117 with 3:21 remaining.

Adebayo finished 3-of-6 from 3-point range for Miami, which shot 34.1 percent (14-of-41) from distance. Dallas hit 10 of 40 threes (25 percent) and shot 41.9 percent overall.

The Mavericks took their first lead since the opening quarter on Irving's 3-pointer that made it 106-103 with 4:34 left in regulation. Dallas clung to a one-point edge as Irving stepped to the free throw line with 8.2 seconds left, but he made just 1 of 2 to leave the door open for the Heat.

Butler capitalized with a dunk off a Duncan Robinson feed with 4.3 seconds remaining, and the game went to overtime after Spencer Dinwiddie's long 3-point attempt at the buzzer went in and out.

Dinwiddie finished with 7 points after shooting 1-for-12 overall, including 0-for-9 on 3-pointers.

There were three lead changes in the first quarter that ended with Miami on top 33-28. The Mavericks missed their last six shots in the quarter, allowing the Heat to close the period on a 9-0 run.

Miami shot just 28.6 percent in the second quarter - including 1-of-10 on 3-pointers -- but still entered halftime leading 56-51.

Just like the second quarter (23-23), the third period was played to a draw (33-33), leaving the Heat with an 89-84 lead heading into the fourth.
