MIAMI -- Jamaal Tinsley scored 26 points, Jermaine O'Neal started a crucial fourth-quarter run with three straight baskets and the Indiana Pacers extended their dominance of the Miami Heat with a 106-103 win Saturday night.
Jermaine O'Neal finished with 24 points and Danny Granger added 16 for Indiana, which started the final period on a 14-4 run to take control and has now won 18 of the past 22 regular-season meetings with Miami.
Dwyane Wade finished with 24 points, but his potentially game-tying 3-pointer bounced off the rim as time expired.
Udonis Haslem also scored 24 for Miami, which fell to 2-8 at home and 6-17 overall -- the fourth-worst record through 23 games in franchise history. Daequan Cook scored 14 points and Ricky Davis finished with 13 for the Heat. Shaquille O'Neal finished with 12 points on 4-for-7 shooting before fouling out.
Indiana led by 11 midway through the final quarter, but Miami rallied and pulled to 103-100 on a free throw by Cook with 39.5 seconds left.
The Heat got the stop they wanted on the next possession -- but Jeff Foster grabbed the offensive rebound, Miami couldn't catch up with any one for a clock-stopping foul and Kareem Rush's layup with 5.8 seconds left made it a five-point game.
Davis made a 3-pointer with 3.7 seconds left, drawing Miami to 105-103, and Tinsley made one free throw a half-second later for what became the final margin.
Tinsley was 10-for-27 from the floor, three shots more than his previous season-high. Rush finished with 14 for Indiana, which has alternated wins and losses in each of its last nine games.
Miami made nine of its first 10 shots, most of them around the rim, and got out to a quick 21-15 lead. Wade threw alley-oop lobs to Haslem and Dorell Wright for dunks on consecutive possessions in the early going, then added a layup of his own with 4:19 left in the period.
But even shooting at that kind of clip -- the Heat cooled to 71 percent for the entire quarter and 61 percent for the half, compared with 40 percent by the Pacers -- Miami only led 55-52 heading into intermission.
The reason was simple: Indiana had 10 offensive rebounds in the half, compared with zero by the Heat, and turned those extra chances into eight second-chance points to keep close.
It didn't hurt that Tinsley was an offensive force, too.
He came into the game averaging 13.7 shots and 14.9 points, and exceeded both of those in the first half alone. Tinsley was 7-for-19 in the opening two quarters, finishing with 17 points -- more than double his 8.1 career average when facing Miami.
The third quarter remained close, with 10 lead changes and six ties in that period alone. Jermaine O'Neal went 3-for-3 in the quarter with eight points, but Miami took a 79-78 edge into the final 12 minutes after Cook tipped in his own miss with 2.0 seconds remaining.
But Jermaine O'Neal opened the fourth with another 3-for-3 effort -- this in the opening 2:12 -- and the Pacers took what was their biggest lead when he cut across the lane for a layup that put Indiana up 84-79.
That was just the beginning of the Pacers' pullaway.
Granger and Troy Murphy hit 3-pointers to stretch the lead to seven, and Tinsley -- who took 22 shots in the game's first 25:18, then didn't take another for the next 13:46 -- connected on another 3-pointer with 6:56 left for a 95-85 lead.
The Heat, who had no steals in Thursday's loss to Washington, made six in the first quarter Saturday. ... Chris Quinn's streak without a turnover ended at 135 minutes, 25 seconds, when he stepped out of bounds after taking a pass from Wade in the right corner late in the opening period. ... Former Florida Marlins pitcher Dontrelle Willis, who was traded earlier this offseason to the Detroit Tigers, was in the crowd and received a warm ovation.
