The air-conditioning system in San Antonio has been fixed and LeBron James attempts to move past a dreadful fourth-quarter experience as the Miami Heat seek to bounce back from a Game 1 loss when they visit the Spurs in Sunday's Game 2 of the NBA Finals. James experienced severe cramping and dehydration issues and missed most of the final 7 1/2 minutes as temperatures soared above 90 degrees due to an electrical malfunction at AT&T Center. San Antonio closed with a 31-9 spurt for a convincing 110-95 victory.James was affected much more than any other player in Thursday's oven-like conditions and told reporters on Friday that he received 2 1/2 bags of intravenous fluids afterward. "For obvious reasons, I was angry, I was disappointed in myself," James said. "I did everything that I needed to do to prepare for this game, prepare for this moment and to feel like my body failed me, I was angry in the fact that I couldn't help my team get over the hump." James departed with 3:59 remaining after he scored a basket to pull the Heat within 94-92 and the Spurs went on a game-ending 16-3 surge after he departed.TV: 8 p.m. ET, ABC ABOUT THE HEAT: James scored 25 points in 33 minutes before exiting, and he first became concerned about the conditions in the first half. He loaded up on fluids at halftime but his body was unable to hold up and he was in the game for only 34 seconds over the final 7:31 before heading to the locker room prior to the end of the contest. Miami coach Erik Spoelstra told reporters the Spurs should be fined if the situation happens again. "We're not making any excuses for it," Spoelstra said. "It was an extreme, unfortunate situation for both teams. It probably won't happen again, ever."ABOUT THE SPURS: While James couldn't hold up in the heat, San Antonio veteran Tim Duncan thrived with 21 points on 9-of-10 shooting to go with 10 rebounds. The 38-year-old power forward played 33 minutes and operated at will in the interior. "Every once in a while, I get a jump shot from 15 to 18 feet, but mostly my effective range is in there right now," Duncan said during Friday's media availability. "I'm going to pick-and-roll and try to get open shots and try to take advantage of the rotation if they're trapping." Duncan shot 49 percent against Miami in the 2013 Finals while averaging 18.9 points and 12.1 rebounds.BUZZER BEATERS 1.
