Thunder 112, Mavericks 91: Russell Westbrook scored 24 points and Kevin Durant added 19 as Oklahoma City defeated visiting Dallas for the third time this season.

Unlike the first two meetings, both of which were decided in overtime, this one was over early. The Thunder led by 25 at the half and cruised from there to improve to 21-3 at home.

Shawn Marion poured in a season-high 23 points for the Mavericks, while Dirk Nowitzki had just 10 on 3-of-11 shooting in his return after missing two games with a leg injury.

Durant and Westbrook combined for 32 points as Oklahoma City cruised to a 68-44 halftime lead, and they continued their dominance in the third quarter. They combined for the Thunder's first seven points of the period to keep Dallas at bay, and Westbrook added back-to-back layups later in the quarter as the Thunder breezed to a 92-67 lead after three.

Both teams turned to their benches for most of the final period. DeAndre Liggins' layup with 9:11 remaining made it 101-71, and Eric Maynor and Reggie Jackson added 3-pointers to cap the rout.

GAME NOTEBOOK: Durant, who was considered questionable with a back injury, has scored 111 points in three games against Dallas this season. ... The Mavericks were 3-for-16 from 3-point range. ... Kevin Martin scored 17 points off the bench for the Thunder.
