BOSTON — Jayson Tatum got into a shootout with Stephen Curry, and the Celtics came out on top.

Tatum scored 44 points – the second-highest total in his career – and Kemba Walker made a 3-pointer with 24 seconds left to help Boston beat the Golden State Warriors 119-114 on Saturday night.

“He’s incredible,” Walker said. “He can score with the best of them. He’s making the right plays out there. He was unbelievable. We needed every bucket he had tonight.”

Curry scored 47 points, including a 3-pointer to cut Golden State’s deficit to two points with 19 seconds left. But he missed a shot from just inside half court on the Warriors’ next possession, dooming their last chance for a win.

The Celtics earned their sixth straight victory and their eighth in their last nine.

“It took everything,” said Walker, who scored 26 points and grabbed his eighth rebound after Golden State’s last shot and bounced the ball vigorously in celebration as the clock ran out. “It was a hard-fought game. We knew it was going to be tough. These guys are playing so well. Obviously they’ve got one of the best players in the world. He’s incredible.”

Andrew Wiggins scored 22 points and Draymond Green had 10 rebounds for the Warriors, who had won four in a row and led by as many as 16 points in the second quarter before Boston ran off 21 of the next 23 points to take the lead in the third.

Back-to-back 3-pointers from Green and Curry gave the Warriors a 109-103 lead in the final minutes before Walker sank a pair of free throws and Tatum hit a 3-pointer to make it a one-point game.

“I’m not really enjoying them going back and forth,” Green said. “I’m not enjoying Jayson Tatum scoring. … I’m thinking, ‘We need a stop.’”

After a few unsuccessful trips up the court, the Celtics worked the ball around to an open Marcus Smart beyond the 3-point line. He stood there, with no one coming out to cover him, before sinking the shot to give Boston a 111-109 lead.

Kevon Looney made a putback to tie it before Tatum drove to give the Celtics the lead for good with 48 seconds left.

After Walker’s 3-pointer gave the Celtics a five-point lead, Curry drilled a corner 3 to make it 116-114 before Tatum sank two free throws with 14 seconds left to clinch it.

“This was a real NBA game,” Warriors Coach Steve Kerr said. “I told them how proud I was, the level of competition and the battle, it was phenomenal to watch.”

Curry put a scare into even the opposing crowd when he buckled to the court with 7 minutes left, apparently because of a turned ankle. He remained hunched over the ball until Tatum tied it up and forced a jump; Curry then got up and limped around in a circle before nodding his head to say he was OK.

About 90 seconds later, Golden State’s Juan Toscano-Anderson went over the scorer’s table to save a loose ball; even as the officials nearby waved frantically for help, Curry wound up with it and hit a 3-pointer that gave the Warriors a 103-101 lead.

After a whistle, Toscano-Anderson was helped back up. He left the court holding a towel to the right side of his head and did not return to the game.

“That’s a competitor,” Kerr said. “Juan is a guy … you want that guy on your team. That’s all.”

But the Celtics scored the last 10 points of the half and continued with an 11-2 run to start the third quarter and open a 71-68 lead. Boston led 78-71 before Golden State ran off nine straight points, getting back-to-back 30-footers from Curry to regain the lead.
