BOSTON -- Jason Terry hit a tiebreaking 3-pointer with 35 seconds left in overtime and the Boston Celtics rallied after blowing a big lead in regulation and beat the Atlanta Hawks 107-102 on Friday night.
The Celtics blew a 12-point fourth-quarter lead and trailed by four in overtime before outshooting the Hawks from beyond the arc in overtime.
Pierce finished with 27 points, seven rebounds and seven assists. Kevin Garnett had 17 points and eight rebounds and Terry scored 19, 11 more than Atlanta's reserves combined.
Al Horford added 22 points and Devin Harris scored 12 for Atlanta. Four starters scored in double figures for the Hawks, but only two other players scored at all for Atlanta in its fourth loss in five games.
The Hawks did make it a thrilling finish in a game Boston appeared to have in hand after a 10-0 run early in the fourth quarter. Atlanta still had time and didn't panic, using a 13-4 run to get back in it and force overtime.
Kyle Korver's 3-pointer with 1:31 left tied it at 92-all and was just the second field goal by a reserve for the Hawks. Pierce answered with a jumper, then Smith set up Horford on an alley-oop dunk to tie it up again.
The Hawks led 98-96 in overtime when Green got lucky for the Celtics with a 3-pointer that bounced high off the rim initially, but somehow stayed on target and went in after two more fortunate bounces and the Celtics had their first lead of overtime at 99-98. Smith answered right away with a 3-pointer, which Pierce matched with 1:37 left to put the Celtics ahead 102-101.
It was tied at 102 when Terry continued the 3-point frenzy on a 25-footer with 35 seconds remaining.
Atlanta turned it over on a bad pass by Smith and Terry drew a foul, sealing the game with a pair of free throws.
