BOSTON — Jayson Tatum made two twisting, driving baskets in the final 15 seconds and finished with 31 points Sunday night, leading the Boston Celtics to a 111-110 comeback victory over the Washington Wizards despite 46 points by Bradley Beal.

Kemba Walker scored 21 points for the Celtics, and Daniel Theis had 20 points and nine rebounds. Boston, which beat Indiana on Friday, has won consecutive games for the first time since late January.

Russell Westbrook had 24 points and 11 rebounds for the Wizards, who had won seven of eight. Davis Bertans added 20 points.

The Wizards led 110-105 after Beal’s driving basket with 47 seconds left before the Celtics sliced it to one on back-to-back baskets by Tatum, including an acrobatic shot in the lane with 15 seconds left.

Washington then turned the ball over before Tatum’s twisting bucket gave the Celtics a 111-110 edge with 4.7 seconds left.

“I think it’s just a feel for the game,” Tatum said of his clutch shots with players around him. “You use your instincts. I’ve been playing basketball since I was 3 years old.”

“He’s a special talent,” Beal said of Tatum. “He’s an All-Star for a reason.”

Beal got trapped in front of Boston’s bench and fired up a shot that bounced off the rim as the buzzer sounded.

“It was a hard-fought effort by both teams. Somebody had to lose,” Wizards Coach Scott Brooks said. “They made big plays. Tatum made big plays.”

Tatum had struggled the previous two games, scoring just nine and 13 points, respectively.

“Just the person he is, I knew he was going to come back strong,” Walker said.

“We just needed to get a basket and JT got some unbelievable baskets. That’s the type of player he is.”

Coming off his NBA-leading 10th triple-double on Saturday, Westbrook added four assists.

Boston trailed 106-98 after Westbrook’s 3-pointer from the left corner with 2:58 to go, but Tatum’s fadeaway capped a 7-0 spurt with 1:34 to play.

“It means a lot,” Walker said of the comeback. “Just the way we handled ourselves in the huddle. We showed some poise.”

Robin Lopez then nailed a short hook shot and Beal had a driving basket.

“We should have won that game. We were up five,” Beal said. “We did everything we needed to do to put ourselves in position to win that game.”

Beal’s four-point play made it 95-94 with just over five minutes left. He followed a basket by Walker with a 3-pointer and followed with a three-point play, making it 101-96 with 3:57 left.

The Wizards took a while to get going, but they opened the final quarter with an 11-2 spurt to grab their first lead of the game.

The Celtics matched their largest lead of the game on Walker’s 3 from the right wing, giving them a 68-57 edge early in the third quarter, before Beal scored eight of the Wizards’ points during a 12-2 run over a 5:03 stretch.

TIP-INS

Wizards: Bertans has hit two or more 3s in team-record 16 consecutive games. … Missed their first eight shots and didn’t get a basket until Bertans’ 3 just past halfway into the opening quarter.

Celtics: Jaylen Brown missed the game because of left knee soreness. Boston Coach Brad Stevens said Brown “is very much day to day.” Javonte Green replaced Brown, making his fourth career start and second this season.
