With their backs against the wall, the Miami Heat thrived once again Tuesday night, defeating the San Antonio Spurs and staving off elimination.

The Heat pulled off a 103-100 overtime victory, forcing a decisive Game 7 on Thursday.

Mario Chalmers had a breakout game, scoring 20 points. LeBron James added 32 as the Heat mounted a fourth-quarter comeback and battled through overtime to even the best-of-seven series at three games each.

“We feel very grateful we have an opportunity to play for a title in a Game 7,” Heat coach Erik Spoelstra said.

The two teams have traded wins since the beginning of the series, and it now boils down to a single game Thursday. That pattern will have to be broken if the Heat is to win its second consecutive championship.

“It was a helluva game,” San Antonio coach Gregg Popovich said. “It’s a game of mistakes. And they ended up on the winning side.”
