MIAMI (AP) -- Miami took a big step forward. Indiana lost two forwards. Suddenly, the road back to the Eastern Conference finals no longer looks daunting for the Heat. LeBron James scored 30 points, Dwyane Wade added 28, and the Heat moved a win away from the NBA's final four with a 115-83 victory over the hurting Pacers last night. The Heat lead the best-of-seven East semifinals 3-2, with Game 6 in Indiana on Thursday night. James added 10 rebounds and eight assists. Shane Battier scored 13 points, Mario Chalmers had eight points and 11 rebounds, and Udonis Haslem finished with 10 points for Miami, which never trailed. Paul George scored 11 points for Indiana, with starting forwards Danny Granger and David West adding 10 points apiece. Granger left with a sprained left ankle in the third quarter, and West left with what the Pacers called a left knee sprain at the end of that period. Miami shot a franchise playoff-record 61 per cent, best of any team in the playoffs this season. It was an 11-point game when Granger departed early in the third quarter, and the Heat outscored the Pacers by 21 the rest of the way. After losing two of the first three games of the series, the Heat are in control once again -- getting there after a wire-to-wire win Tuesday, with just one time where things seemed in some doubt. The margin was as big as 37 points in the final moments. Miami, which had gotten into quick deficits in each of the first four games, was the team that started hot in Game 5, running out to a 19-8 lead on the strength of three 3-pointers from Battier -- who had been 2 for 19 from the field in the first four games of the series. Battier left his mark in many ways, even stopping a 3-on-1 Indiana break to set up a score by Wade at the other end. So now the Heat are one win from the East finals, after a series filled with twists and turns.
