INDIANAPOLIS -- LeBron James scored 22 points and the Miami Heat rediscovered their offensive punch, routing the Indiana Pacers 114-96 on Sunday night to take a 2-1 lead in the Eastern Conference finals.
Game 4 is Tuesday night in Indianapolis.
It was vastly different from the first two games when the Heat couldn't pull away.
Miami used an 8-2 run to open up a 10-point lead in the second quarter led 70-56 at halftime -- Miami's biggest lead in the series.
Indiana didn't get closer than seven the rest of the way.
It was a rare letdown from one of the NBA's top defensive teams.
Miami shot 54.5 percent from the field, was 24 of 28 from the free-throw line, matched its highest-scoring quarter of the playoffs this season (34) in the first, broke the franchise's postseason scoring record for a half with 70 points and tied a franchise playoff record with only one first-half turnover.
The combination was the perfect remedy for Miami, which needed James' buzzer-beating layup to win Game 1 in overtime and turned the ball over twice in the closing seconds of Game 2, a 97-93 loss. The Heat hadn't led by more than five in either of those two home games.
On Sunday, Miami got major contributions from a handful of players and left nothing to chance.
It traded baskets through the first quarter, building a 34-30 lead and getting the Pacers out of their grind-it-out style, then opened up the second quarter on an 8-2 run to make it 42-32. Indiana couldn't get closer than seven the rest of the half and when James knocked down a 15-foot jumper with 1.3 seconds left, the Heat had the record.
Indiana was a different team to start the second half, getting back-to-back 3-pointers and a three-point play from George Hill. Lance Stephenson followed that with 1 of 2 free throws to cut it to 74-67.
But 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 closed to 101-87 midway through the fourth but couldn't any closer. It was only the third time this season the Pacers lost at home by double digits. Indiana fell 97-75 to Oklahoma City in April and 105-95 in the regular-season finale to Philadelphia when coach Frank Vogel rested four of five starters.
