MIAMI (AP) — Kevin Durant and Russell Westbrook combined to score 54 points, more than any set of teammates had managed in a game against Miami all season.
Oklahoma City needed them to score at least three more.
That didn't happen, and an NBA Finals rematch went just as last year's title series did — to the Heat.
LeBron James had 29 points, nine assists and eight rebounds, Dwyane Wade scored 21, and the Heat survived a frantic finish to beat the Thunder 103-97 on Tuesday night, a game where Durant and Westbrook both missed potential tying 3-pointers in the final seconds.
"A great game to play," Thunder coach Scott Brooks said, "and a great game to coach."
For the Heat, it was just a little greater.
Mario Chalmers scored a season-high 20 for the Heat, who were 19 for 19 from the foul line, the second-best effort in franchise history behind only a 30-for-30 game in Boston on March 24, 1993. Chris Bosh added 16 points for Miami, which has beaten the Thunder five straight times dating to last June's title series.
"Felt a little bit like a different month," Heat coach Erik Spoelstra said. "Regardless of what your script is coming into the game, when you play this team, it's not going to go according to script. They're too good."
It's the first losing streak of the season for the Thunder, who had been 4-0 after losses. Serge Ibaka and Kevin Martin each scored 15 for Oklahoma City.
The game had a little of everything — a fast start by the reigning champions, a one-handed dunk by James on an offensive rebound that will be added to his copious highlight reel, a scrum after a hard foul that led to double-technicals on Wade and Ibaka early in the fourth, an easy rally by the Thunder from an early double-digit deficit, and even workout partners in Durant and James barking back and forth in the final minutes.
Such was the intensity that James slumped over the scorer's table with 1:08 left, exhausted.
"I'm tired as hell right now," James said — and that was more than an hour after the game ended.
With good reason. On an emotional day, there was a wild finish.
Wade lost the ball on an ill-advised, behind-the-back dribble, and the turnover set up Durant for a two-handed dunk that got the Thunder within 96-95 with 44.1 seconds remaining.
Needing a stop on the next trip, the Thunder instead forgot to play defense. Kendrick Perkins and Ibaka both were confused on the ensuing Miami possession, and Bosh was left alone to take a pass from James and throw down a dunk that restored Miami's three-point edge.
"We went over and helped," Durant said. "We just needed to help on the backside. There was miscommunication but we still had a chance to go into overtime."
