Boston Celtics at Oklahoma City Thunder

Tatum scores 27 points, Celtics rally to beat Thunder 111-94

Jaylen Brown added 25 points to help the Celtics close out a four-game trip and even their season record. Boston had lost five of six before winning at Milwaukee on Friday and at Oklahoma City on Saturday.

A loss would have damaging for a squad that has struggled to find consistency this season.

“This was one where we had to find a way because we can’t keep going back and forth," Celtics coach Brad Stevens said. 'We’ve got to establish some momentum here.”

Moses Brown scored a career-high 21 points and tied a Thunder record with 23 rebounds. The team announced before the game that veteran center Al Horford will be inactive the rest of the season while the team’s young players develop. Brown moved into the starting lineup and set a franchise record for rebounds in a half with 19 before the break.

“I just wanted to come out and set the tone with my energy and just being active around the basket," he said. "Just knowing how to get space and knowing how to box out and utilizing my height and my strength.”

Theo Maledon added 22 points for Oklahoma City.

Brown had 17 points in the first half as the Thunder took a 52-47 lead. He made 6 of 6 field goals and 5 of 6 free throws in just 16 minutes.

The Thunder led 80-76 heading into the fourth quarter. Jaylen Brown kept the Celtics in it with 13 points in the third.

Back-to-back 3-pointers by Luke Kornet put the Celtics up 88-82 early in the fourth. The Celtics acquired Kornet from the Chicago Bulls in a three-team deal that involved the Washington Wizards.

A fast-break dunk by Tatum put the Celtics up 95-82, and Boston cruised from there. The Celtics shot 56% in the fourth quarter and outscored the Thunder 35-14. Oklahoma City made just 5 of 17 shots in the final period.

The fourth quarter offered a glimpse of the way the Celtics want to play the rest of the season.

“We’ve got a lot of talent out here individually, but that’s not going to beat anybody," Smart said. "That’s not going to beat teams. Teams are getting better, teams are good, teams are doing their homework.”

GOOD COMPANY

He tied Adams' single-game rebounding record, which was set Dec. 19, 2018 at Sacramento. Adams also had the record for rebounds in a half with 15, in the same game against Sacramento.

QUOTABLE

Horford on his status: “When I arrived, I understood the direction of the team, we had a great individual plan in place for me, and I feel like as a result I’ve played really good basketball for the Thunder. At the same time, I know what it’s like to be a young, aspiring player, and at this point in the season I understand how important playing meaningful minutes is for their careers and their development."
