Russell Westbrook's 3-pointer with 2:24 remaining sparked a 9-0 Oklahoma City run to end the game as the Thunder edged the Dallas Mavericks 95-91 Monday night at Chesapeake Arena.
The Thunder (30-8) trailed 91-87 before Westbrook's trey. Serge Ibaka, Kevin Durant and Westbrook would add five free throws down the stretch and Kendrick Perkins came up with a big defensive play to preserve the win.
After Ibaka's free throws put the Thunder ahead 92-91, Perkins blocked Jason Terry's shot attempt with 22 seconds and the Mavericks were forced to foul.
Dallas led by as many as ten points late in the second quarter and took a 52-45 advantage at the half. But, Oklahoma City opened the second half with seven straight points to jump back in the game and would take over the lead with another 7-0 run late in the third.
Dirk Nowitzki scored nine of his 27 points in a less than two minute span late in the fourth on three straight 3-pointers -- the last of which gave the Mavs a 91-87 lead with 2:46 to play.
It would be the last points for Dallas. Nowitzki's magic faded as he missed his next shot, then threw the ball away on Dallas' next possession.
Westbrook led the way for Oklahoma City with 24 points while Durant added 22 and James Harden scored 16 off the bench. The Thunder won despite shooting just 38-percent from the field.
Oklahoma City had a 19-point advantage at the free throw line and won the rebounding battle 45-to-36, including a 14-rebound game from Kendrick Perkins. Ibaka was a defensive force with six blocked shots.
Oklahoma City continues a five-game homestand Wednesday against the Phoenix Suns, winners of three straight games.
