INDIANAPOLIS (AP) - The Indiana Pacers didn't see this version of Udonis Haslem coming. There was no reason to. Haslem, a veteran forward who had scored in single digits in six of his previous seven playoff games, finished with 17 points on 8-for-9 shooting to help the Miami Heat beat the Pacers 114-96 in Game 3 of the Eastern Conference finals on Sunday night. The Heat took a 2-1 lead in the series and regained homecourt advantage with Game 4 set for Tuesday night in Indianapolis. Haslem went a quiet 1-for-7 from the floor in the first two games of the series, but he looked for his shot early and often in Game 3. His mid-range jumpers constantly left 7-foot-2 center Roy Hibbert out of position. Hibbert had been playing slightly loose defense on Haslem and Chris Bosh to help protect the rim and the lane against LeBron James and Dwyane Wade. Hibbert said Haslem's effectiveness forced him to change his approach. "I think he was really the guy that pushed them, the catalyst for them," he said. Just him hitting those shots really made us have to think on defense. Who do we guard? Do we guard the paint, or do we have to go out to the shooters out in the corner. Pacers coach Frank Vogel was heavily criticized for taking Hibbert out of Game 1 before James' game-winning layup. Vogel said he made the move because he was worried Bosh would get open for an easy jumper. The Heat spent 48 minutes showing Pacers fans why Vogel's Game 1 decision might not have been such a bad idea. "That's what Miami does, they space you out," he said. They make it difficult to have a rim protector in the game at all times. They challenge you to keep a guy at the rim and still make them close out to an 18-foot jump shooter. We have to account for that. While Haslem and Bosh pulled Hibbert and power forward David West away from the basket, James took over as the Heat's post presence, overpowering and dominating All-Star forward Paul George. James, bouncing back after two late turnovers cost Miami in Game 2, had 22 points, four rebounds and three assists. Hours after Wade learned he would only be tagged with a flagrant foul from Game 2 and not a suspension, he finished with 18 points, eight assists and four rebounds. Bosh added 15 points and three rebounds, and all five Miami starters reached double figures. Miami outscored Indiana 56-32 in the paint, but perhaps that much should be expected from a team with this much scoring punch - one that has won 23 of its last 24 games on the road. The Heat shot 54.5 percent against a Pacers team that finished the regular season with the NBA's best defensive field goal percentage and also made 24 of 28 free throws. But the biggest difference between the first two games and Sunday night's rout was James' work on the inside. "It was something we wanted to get just to help settle us and get into a more aggressive attack," Heat coach Erik Spoelstra said of the decision to post up the 6-foot-8 James. Now it's the Pacers turn to adjust. West led Indiana with 21 points and 10 rebounds, while Hibbert had 20 points and 17 boards. George finished with 13 points and eight assists, not nearly enough for the Pacers to remain perfect at home in the postseason. A few minutes later, James did it again, making a 15-footer with 1.3 seconds left in the half to give Miami a 70-56 lead at the break - and the franchise record. Miami countered with a 9-4 run, extended the lead to 91-76 after three and made it 99-78 early in the fourth. Indiana never challenged again - the 18-point margin matching Indiana's worst home loss of the season - even though James scored only four second-half points. "If you're not perfect guarding them, they'll do what they did to us tonight," Vogel said. NOTES: Miami's best scoring half before Sunday was a 68-point effort against Chicago on April 24, 2006. ...
