Mavericks 109, Thunder 86

OKLAHOMA CITY — Forward Shawn Marion scored 19 points to lead the Dallas Mavericks to a 109-86 victory over the Oklahoma City Thunder Sunday at the Chesapeake Energy Arena.

The 23-point loss represented the largest margin of defeat for the Thunder this season. Dallas snapped an 11-game losing streak to Oklahoma City.

With Thunder guard Russell Westbrook sitting out, the Oklahoma City offense ran through forward Kevin Durant much of the night. However, the team didn’t respond like it had when Durant ran the offense during Westbrook’s injury absence. Oklahoma City found itself down by 21 heading into the fourth quarter.

No matter what Oklahoma City (48-18) tried, Dallas had an answer to rebuff any fourth-quarter rallies. From 3-pointers by forward Vince Carter to fade-away jumpers by forward Dirk Nowitzki, the Mavericks (40-27) scored at will to start the quarter and put the contest away early.

Carter came off the bench to score 18 points while Nowitzki added 17 on 6-of-12 shooting. Guard Jose Calderon had 16 points and seven assists.

Durant led all scorers with 30 points on 8-for-20 shooting. It was his 31st straight game of scoring at least 25 points.

Forward Serge Ibaka added 19 points and six rebounds for the Thunder. Guard Reggie Jackson, who started in Westbrook’s place, had 13 points and three assists.

Dallas came out firing from behind the arc in the first period. Led by Calderon, the Mavericks were 4-of-8 from 3-point range as they took a 29-23 lead.

After falling behind by 10, Durant and Ibaka picked up the scoring for the Thunder. They closed the deficit to 50-46 before Marion led Mavs on a 9-2 run to end the half.
