The Thunder finished the first quarter on an 11-1, capped by a buzzer-beating deep jumper from Derek Fisher. That run extended to 25-7 midway through the second quarter as the Thunder opened up a 46-30 lead and looked like they were starting to pull away.
But Dallas fought back, going on a 17-4 run in just over three minutes to make it a tight ballgame. Dirk Nowitzki has 20 points to lead the Mavs.
