James quickly answered after Oklahoma City tied the game for the first time at 60-all midway through the third, banking in a shot and powering in for a layup and a quick four-point lead. The Heat pushed the lead back to five but the Thunder kept coming, finally pulling ahead for the first time when Westbrook darted into the lane and was fouled while scoring with 16.4 seconds remaining, the free throw making it 74-73.
Baskets by Durant and Sefolosha to open the fourth pushed it to a five-point lead, and the Heat never recovered.
Notes: Battier’s 13 first-half points equaled his high for the postseason. He and Westbrook were also called for double technical fouls after Westbrook’s basket with about 30 seconds left in the half. … The Thunder, 23-59 in 2008-09, duplicated the feat of the Heat, who also reached a finals within three seasons of a 25-win season. Miami was 15-67 in 2007-08 before playing for the title last year.
