Danny Green has one great skill, and fortunately for the San Antonio Spurs, he revealed it at the right time Thursday.

Green, an adept 3-point shooter, made three long-distance shots in the fourth quarter, and the Spurs defeated the Miami Heat 110-95 Thursday in the first game of the NBA Finals.

The 26-year-old guard scored 11 of his 13 points in the final quarter.

Last year, Green made set an NBA Finals record with 27 3-pointers in San Antonio's seven-game loss to Miami.

"That's what he does," Spurs coach Gregg Popovich said. "If he's not going to do that, then we might as well play somebody else. That's the honest to God's truth."

The Spurs finished with a 31-9 run. They hit 14 of 16 shots in the fourth quarter, including all six 3-point attempts.

The game was played under horrible conditions. The air conditioning at AT&T Center malfunctioned because of an electrical failure, and temperatures on the court reached above 90 degrees.

Miami forward LeBron James clearly struggled with the heat. He scored a game-high 25 points but was forced to leave the game a few times because of cramps, a condition he endured in the past.

When James departed with 7:31 remaining, the Heat led by two points. He returned briefly but then left for good.

"I was going to try to give it a go, and (coach Erik Spoelstra) said no," James said to a pool reporter following the game. "It sucks at this point in time in the season. ... It was frustrating sitting out. ...

"My muscles spasmed 10 out of 10. The best thing for me to do was not move."

James was receiving treatment after the game and did not speak to the media.

"We're used to having the hotter arena at this time of year," Spoelstra said. "But both teams had to deal with it."

The temperature affected James more than anybody, though.

"It felt like a punch in the gut when you see your leader limping back to the bench," Spoelstra said. "At one point, he was getting back up with 3 1/2 minutes to go. I looked at him and said, 'Don't even think about it. You can't even move.'"

Heat guard Ray Allen pointed out that other factors contributed to the defeat.

"We made mistakes," Allen said. "We didn't execute at both ends."

The Spurs won despite committing 23 turnovers that Miami converted into 28 points. The Heat made 18 turnovers that San Antonio parlayed into 27 points.

Forward Tim Duncan led the Spurs with 21 points, and he grabbed 10 rebounds. Guard Tony Parker produced 19 points and eight assists. Guard Manu Ginobili contributed 16 points and 11 assists.

The Spurs trailed by seven early in the fourth quarter but rallied behind Green. After missing all five of his shots from the field in the first three quarters, Green made four in a row midway through the fourth quarter, including three 3-pointers.
