The 18-game streak ties the seventh longest in NBA history, and is the league's best since the Boston Celtics won 19 straight during the 2008-09 season. Miami will try for No. 19 when it hosts Atlanta on Tuesday night.
The win also gave Miami (47-14) a victory over every NBA team this season. The Heat lost both previous meetings with Indiana.
David West scored 17 of his 24 points in the first half for the Pacers, who fell nine games behind Miami in the Eastern Conference standings. Roy Hibbert scored 15, D.J. Augustin had 14 and Paul George scored 10 for Indiana.
Raptors 100, Cavaliers 96
Cavaliers star guard Kyrie Irving was knocked out by an apparent shoulder injury late in the third quarter as Cleveland lost for the fourth time in five games.
Irving was hurt when he collided with Toronto rookie Jonas Valanciunas on a baseline drive with 2:04 left in the third. He shot the resulting free throws one-handed. Irving made the first but missed the second before walking off and heading to the locker room. He finished with 12 points.
Irving missed 11 games between Nov. 21 and Dec. 8 with a broken finger. He also sat out three games between Feb. 26 and March 1 with a sore right knee.
Lakers 90, Bulls 81
The Lakers improved to 33-31, the first time this season they have been two games over .500. They also moved one-half game ahead of the Utah Jazz and into sole possession of the No. 8 and final playoff spot in the Western Conference.
The Lakers led almost throughout, only briefly falling behind by two points in the second quarter, and led by as many as 18 in the third period.
Howard made 8 of 14 shots from the floor but missed all five free throws. His 21 rebounds marked the fourth time this season he's grabbed at least 20.
Thunder 91, Celtics 79
The Thunder limited Boston to 25 percent shooting in the second half after the Celtics shot 51 percent in the first. Oklahoma City used an 11-2 run at the start of the fourth quarter to close it out.
The Celtics had pulled within 68-65 after three quarters before going without a basket for the first 5 minutes of the fourth, and they never could recover.
Magic 99, 76ers 91
ORLANDO, Fla. -- Jameer Nelson had 24 points and 10 assists, and Nik Vucevic added 14 points and 17 rebounds. The win ended the Magic's seven-game home losing streak, their longest skid in Orlando since 2003-04.
Philadelphia has dropped five straight and 13 in a row on the road.
Hornets 98, Trail Blazers 96
NEW ORLEANS -- Ryan Anderson capped a 20-point performance with a layup as he was fouled with 1.8 seconds left, and the Hornets snapped a three-game skid.
Anderson also hit a 3 with 15.6 seconds left that gave the Hornets a 95-93 lead, but Portland rookie Damian Lillard reached the 20-point mark for a sixth straight game by draining a 3 with 11.2 seconds left.
Greivis Vasquez, who also had 20 points, then dribbled out of traffic along the perimeter and found Anderson inside for the winning bucket.
Anthony Davis had 18 points and 10 rebounds for New Orleans.
Mavericks 100, Timberwolves 77
Brandan Wright added 13 points and seven rebounds for the Mavericks, who have won three straight and four of their last five in a last-ditch push for the playoffs. They entered the day in 11th place in the West, three games out of the eighth spot.
Derrick Williams had 18 points and nine rebounds for the lethargic Timberwolves, who had no energy on the second night of a tough back-to-back that started in Denver. J.J. Barea scored 16 points, but Minnesota's bench managed just six other points. The Wolves are 6-25 since Kevin Love broke his hand for the second time on Jan. 8.
Bucks 115, Kings 113
SACRAMENTO, Calif. -- Monta Ellis had 29 points and nine assists and the Bucks survived a late comeback by the Kings to earn their second straight victory and sixth in seven games. Before the current hot streak, Milwaukee had dropped nine of 11 games.
Ellis had 10 fourth-quarter points for the Bucks, who were outscored 33-30 in the period.

Clippers 129, Pistons 97
LOS ANGELES -- Blake Griffin led seven players in double figures with 22 points on 9 of 12 shooting and the Clippers beat the Pistons for their 10th win in 13 games.
Chris Paul had 20 points and 14 assists, and Caron Butler added 15 points before leaving in the third quarter with a left elbow contusion. Matt Barnes had 16 points, DeAndre Jordan added 13 points and seven rebounds, Willie Green 11 points and Chauncey Billups 10 points.
The Clippers set season highs for points scored and shooting percentage (62) while leading the entire game. Their old high of 125 points came in a win over the Lakers last month.
Jose Calderon was one of five Pistons in double figures with 18 points as they lost their fifth in a row overall, fourth straight to the Clippers, and fell to 0-11 on the road against Western Conference opponents.
Pistons coach Lawrence Frank missed his third straight game because of a family matter. Assistant Brian Hill, who is running the team, said he doesn't expect Frank back for the remainder of the four-game trip.
