MIAMI – LeBron James finished with 29 points, nine assists and eight rebounds, Dwyane Wade scored 21, and the Miami Heat survived a frantic finish to beat the Oklahoma City Thunder, 103-97, in an NBA Finals rematch Tuesday.

Mario Chalmers scored a season-high 20 for the Heat, who matched the franchise's best 25-game start at 19-6. Chris Bosh added 16 for Miami, which has beaten the Thunder five straight times going back to last June's title series.

Kevin Durant scored 33 points and Russell Westbrook added 21 for Oklahoma City, but both Thunder stars missed potentially game-tying 3-point attempts in the final seconds. Serge Ibaka and Kevin Martin each added 15 for the Thunder, who have dropped two straight for the first time this season.
