BOSTON (AP) — Kyrie Irving extended the game with a clutch shot, then ended it with two more in overtime.
Irving scored six of his 40 points in overtime, hitting back-to-back 3-pointers while leading Boston back from a five-point deficit as the Celtics beat the 76ers 121-114 on Tuesday night.
“Just competition at its highest. I love going against the best. It’s not too often you get to do that in the regular season, especially on a holiday like Christmas,” said Irving, who also pulled down 10 rebounds. “I got to open presents with my family this morning then come into work. It was great.”
It came very close to not being so great for Boston, which needed Irving’s fadeaway jumper from 13-feet out to tie it at 108 with 20 seconds left in the fourth quarter, forcing the OT.
Simmons’ two free throws with 2:15 left to put the Sixers up 114-112, but Philadelphia didn’t score again.
“These are the type of games that challenge you mentally, and we made sure that we stayed with it and finished it,” said Al Horford, who scored just four points but pulled down nine rebounds and helped mitigate the Sixers’ size advantage inside.
The Celtics led 57-51 at halftime, but Philadelphia used a 15-2 run in the third while shooting 60 percent in the period and led 89-86 entering the fourth.
Philadelphia shot 60 percent in the third quarter, hitting five 3-pointers, and led 89-86 entering the final quarter.
It stayed tight through the end of the fourth. Chandler got open for a 3-pointer with 37 seconds left and the Sixers led 108-106, then Irving pulled up for a 13-foot jumper to tie it at 108 with 20 seconds left.
Redick missed a jumper just before the buzzer and the game went into OT.
The Sixers-Celtics rivalry isn’t quite back to where it once was, but it is getting closer. Boston beat Philadelphia 4-1 in the second round of the playoffs last season and won the first two meetings this season, although the Sixers had not yet picked up Butler in a trade with Minnesota before Boston’s 105-87 win on Oct. 16.
The next two meetings are in Philadelphia.
“Obviously those guys have gotten better. It’s definitely tougher — no question,” Horford said.
Irving said Butler had him covered well and forced him to put some extra arch on his game-tying fadeaway at the end of the fourth.
“He hit a tough shot. That’s what he does. That’s why he is the player that he is,” Butler said.
