The Miami Heat came roaring back after losing the first game of the NBA Finals, whipping the San Antonio Spurs 103-84 to even the best-of-seven series at a game apiece.

Five Heat players scored in double figures, led by Mario Chalmers with 19 points, including seven in the decisive third quarter.

LeBron James contributed 17 points for the defending champs, along with eight rebounds, seven assists, three steals and three shot-blocks.

Chris Bosh, who was criticized after the Heat's loss in game one, racked up 12 points, 10 rebounds, four assists, three steals and one shot-block.

The Heat effectively neutralized the Spurs Big Three - Tony Parker, Tim Duncan and Manu Ginobili - as San Antonio suffered their worst defeat of this year's playoffs in front of the capacity crowd at Miami's American Airlines Arena.

No team has ever come back to win the NBA Finals after losing the first two games at home and the Heat were determined not to leave Miami 0-2.

The series now shifts to San Antonio for the next three games.

Game three is Tuesday night at the AT&T Center. EFE
