After starting this season-long six-game homestand with two pretty good wins, the Miami Heat is right back where it was a week ago: 10 games under .500 and still trying to figure out why playing at AmericanAirlines Arena seems to lull them to sleep for a quarter.
The Boston Celtics became the 10th team to beat the Heat on its home court in 14 games, jumping out to a 22-point lead in the second quarter before hanging on for 105-95 victory Sunday night.
Isaiah Thomas led Boston with 23 points and four assists before he was ejected for a flagrant foul with 3:02 to play after he elbowed Justise Winslow in the face and drew blood under Winslow’s right eye.
Avery Bradley added 20 points on a good shooting night (9 of 17) and Al Horford chipped in with 17 points, seven rebounds and a team-high eight assists.
The Heat shot a season-best 52.2 percent from the field, but matched a season-high with 23 turnovers and missed 11 free throws, offsetting very productive nights from Hassan Whiteside (23 points, 17 rebounds and three blocks) and Goran Dragic (31 points, five rebounds, seven assists).
“We’re not talented enough to win like that,” said Dragic, who said he’s grown tired of the Heat falling behind big at home in the first half. “We need to grind those games. We need to play our game defensively. And only like that can we win these kind of games.”
