MIAMI — Josh Smith made a go-ahead layup with 34.7 seconds left in overtime, Joe Johnson scored 19 points and the Atlanta Hawks beat Miami 93-89 on Tuesday night to send the Heat to a fourth straight loss.
Johnson had a game-tying layup with 25.4 seconds left in regulation and two game-sealing free throws with 5.2 seconds remaining in overtime. Jamal Crawford also scored 19 for Atlanta.
LeBron James scored 34 points and grabbed 10 rebounds for Miami, but missed a long 3-pointer at the end of regulation and another 28-foot try as the shot clock was expiring late in overtime and the Heat down by two.
Dwyane Wade finished with 27 points for the Heat, who got 16 rebounds — with no shot attempts — from Joel Anthony.
The Heat had a chance to win it at the end of regulation after Johnson knotted the game, but chose not to call time-out for a final play. Instead, they worked the clock down and set up James for a 28-footer that banged off the side of the rim just before the buzzer.
Miami had three game-tying scores in overtime, the last of those coming when James made a 3-pointer with 51.9 seconds left. The Heat didn’t score again.
Atlanta got 15 points and 12 rebounds from Smith, 15 points from Mike Bibby and 11 from Mo Evans. The Hawks tried a season-high 31 3-pointers, making seven.
Eddie House scored 12 for Miami, and Mario Chalmers added 10.
The Hawks played most of the second half without Al Horford, who sprained his right ankle early in the third and departed with six points and nine rebounds.
Miami’s lead was 70-64 when Wade made a fadeaway jumper with 4:26 left, but on a night where neither team ever enjoyed much in the way of offensive flow, the Heat picked the wrong time to go cold.
Bibby’s fourth 3-pointer of the game with 2:32 left got Atlanta within 72-70. Evans tied it a half-minute later with a pair of free throws, Smith hit two more to give the Hawks the lead, and Bibby made another for a 75-72 edge with 1:23 remaining.
That’s when James tried to take over.
A pair of free throws got Miami within one, and he simply overpowered Bibby for a layup and foul to give the Heat a 77-75 edge — but Johnson sent the game into extra time.
Anthony’s start — just the fifth of his career at power forward — was needed because Chris Bosh sat out with a sprained left ankle. James’ status for the game wasn’t clear until just before game time because he, too, has been hobbled by a sprained left ankle.
“We do have versatility on the roster,” Heat coach Erik Spoelstra said before the game. “This is probably the time it’ll show the most, playing guys that weren’t necessarily playing big minutes, they’ll be able to step up and have their opportunity.”
Anthony must have been listening.
According to STATS LLC, only Dennis Rodman — who had 20 rebounds with no attempted free throws or field goals for San Antonio on Jan. 25, 1994, plus had an 18-rebound, no-shot game for the Spurs three weeks earlier — had at least 16 rebounds in a game without ever trying a shot of any sort.
It wasn’t enough, on a night when there were plenty of rebounds to be had.
Atlanta nearly held the Heat to single digits in the opening quarter, setting the tone for an offensively challenged night all around.
Only Chalmers’ buzzer-beating 3-pointer at the end of the first saved Miami from that indignity, as Atlanta — which forced the Heat into missing 15 of their first 18 shots — ended the opening quarter up 19-11. James started 1 for 8 from the floor, missing his last six tries of the period.
The Hawks’ befuddling of Miami continued in the second. When Bibby hit a 3-pointer with 6:37 to play in the half, Atlanta led 30-17, and the Heat looked totally lost.
It changed quickly.
Miami scored the game’s next 13 points, James getting five of them, including a shot in the lane with 2:47 left — moments after Anthony blocked a dunk attempt by Johnson — that knotted the game at 30. Eddie House’s 3-pointer 42 seconds later put the Heat on top, and Miami took a 35-34 lead into halftime.
The Heat shooting improved in the third quarter as well — up to 46 percent, less than riveting but far better than the showing in the first half. Turnovers, though, were the damning factor.
Atlanta forced six takeaways in the third, getting 13 points off them, more than enough to stay in the game. The Hawks led 58-55 going into the fourth, after a third period that featured five lead changes, four ties and neither team ever leading by more than six.
NOTES: It was the sixth time Anthony has grabbed 10 or more rebounds in his career. His previous best was 13. ... The Hawks re-signed Damien Wilkins to a second 10-day contract earlier in the day. ... Miami next plays Saturday against Toronto, then doesn’t play after that until Jan. 27 in New York.
