SAN ANTONIO (Reuters) - Some torrid fourth-quarter shooting led by Danny Green lifted the San Antonio Spurs to a come-from-behind 110-95 victory over the Miami Heat in the opening game of the NBA Finals on Thursday.

Green scored 11 of his 13 points in the final period as the Spurs hit 14-of-16 shots, including all six from beyond the arc, turning a seven-point deficit into a runaway victory.

LeBron James paced the Heat with 25 points but played only five minutes in the final quarter due to leg cramps. An electrical outage caused the air conditioning to fail at the AT&T Center, creating steamy conditions for both players and fans.

"It sucks at this point in time in the season," said James. "After I made that layup we was down two and, you know, as well as they played we still had a chance. After I came out of the game, they took off. And it was frustrating sitting out and not be able to help our team."

Tim Duncan, who led the Spurs with 21 points, said taking care of the ball made the difference down the stretch. San Antonio had 22 turnovers but was dazzling when it counted.

"We took care of the ball finally," he told reporters. "We had 20-some odd turnovers for 28 points. The last seven or eight minutes we only turned the ball over once or twice. Getting them out of the passing lanes, keeping them in front of us, making them score over us, and we found something that worked on the offensive end."

Tony Parker scored 19 points and Manu Ginobili added 16 for the Spurs, who host Miami in Game Two of the best-of-seven series on Sunday.

James said he welcomes the rest until Sunday's game. "I need it, I need it, I need it," he said. "We're going to start tonight, continue to get the fluids in me and get me ready for Sunday. Sitting on the sideline, if I'm not in foul trouble, is not good for us and not good for me. I look forward to Game Two and go from there."
