DALLAS - The Miami Heat didn't blow this one. Now they're just two wins from being crowned NBA champions.
Chris Bosh made a 16-foot, go-ahead jumper from the baseline with 39.6 seconds left and the Heat held on for an 88-86 victory over the Dallas Mavericks on Sunday night for a 2-1 lead in the NBA finals.
Recent history says this is a huge win for the Heat. The Game 3 winner in a tied finals has won the championship all 11 times since the 2-3-2 format began in 1985.
Miami got into this tight of a series by blowing a 15-point lead in the last quarter of Game 2. The Heat already had wasted a 14-point lead in this game when they went back ahead 81-75 with 6:31 left. They knew Dirk Nowitzki would drive Dallas' rally, but he burned them anyway for 12 straight points - six free throws, a layup, a dunk and a tough jumper.
But after Bosh's clutch shot, Nowitzki's streak ran out. He tried passing out of a double team and threw the ball away, then hit the back iron on a jumper at the buzzer.
"This is a total win," said Dwyane Wade, who led Miami with 29 points and 11 rebounds. "You want to win the game on the defensive end of the floor and we got a stop."
The Heat go into Game 4 on Tuesday night with a chance to do what they did in 2006: win it all on Dallas' floor. They'll need to win that game and the next, on Thursday night.
Bosh, a Dallas native who'd been 0-8 in his hometown, overcame a swollen left eyelid caused by a poke during the first quarter to scored 18 points. He had seven in the fourth quarter.
LeBron James added 17 points and nine assists. But he also had four turnovers, including a pair during the fourth quarter that helped bring Dallas back. Mario Chalmers added 12.
Udonis Haslem had only six points, but his tough defense on the final two possessions saved the Heat. When Nowitzki's final shot from the top of the key missed, Haslem swung his arms and screamed in delight.
Nowitzki finished with 34 points, but didn't get much help. Jason Terry scored 15 and Shawn Marion had 10, but both were shut out in the fourth quarter.
Wade was at his dynamic best from the start, looking like the guy who soared and scored the Heat past Dallas and to the title in '06.
Most of his baskets came in the paint - where the Heat outscored the Mavs, 40-22 - and many of them were spectacular. But he also stemmed Dallas' rally by hitting a go-ahead jumper over Jason Kidd for Miami's second-to-last basket.
James came in talking about being more aggressive, but wasn't. He went more than 6 minutes before taking his first shot, but certainly made it worth the wait - a drive through the teeth of the defense for a powerful dunk. He also had a two-handed jam in the second half that put Miami up by 13.
The Heat just couldn't put the Mavs away. Dallas would surge close or ahead, then Miami would turn it up again. The final 18 minutes played out with both teams realizing any possession could change the game and the series.
Nothing came easy for anyone. Shots were contested, bodies collided for every rebound and guys were flying into the stands after loose balls. Fans stood throughout, wearing their blue gimme T-shirts and fired up by videos such as one featuring encouraging words from Roger Staubach, Troy Aikman, Emmitt Smith, Nolan Ryan and others.
Yet it was the visitors from Miami who walked off celebrating.
Heat coach Erik Spoelstra talked about wanting his guys to get back to their identity of being "an aggressive, attacking team that tries to get into the paint, to the rim, to the free throw line." They followed that script to a 14-point lead late in the second quarter, then fell into the same bad habits they showed at the end of Game 2, letting Dallas get within 47-42 at the break.
Maybe Miami players just got bored because things were coming so easily.
James and Wade seemed to get whatever shot they wanted, whenever they wanted. But they kept trying to get others involved. They especially force-fed Bosh, even though his left eye was swollen from an early, accidental poke by Jason Kidd; he missed 7-for-9 in the first half.
The Heat also made things tough on Nowitzki by keeping him from even getting the ball. He took only two shots in the first quarter. He didn't start getting free until Miami's lead grew and guys were less intense on defense.
n NOTES: Dallas fell to 8-2 at home this postseason. ... The Heat and Mavs have each won a road game this series, which should be no surprise. They tied for the best road record in the NBA this season. ... Bosh was booed as much as any Miami player during pregame introductions. So much for fans cutting the local kid some slack. ... The Mavs fell to 2-1 this postseason in games officiated by Dan Crawford. Dallas came into this postseason having lost 16 of its last 17 playoff games he worked. ... Aikman and Terrell Owens sat about 10 seats apart on the same row. Owens attended games in Miami, too. ... Shades of the 2008 NCAA finals: Chalmers beat the first-quarter buzzer with a 3-pointer.
