OKLAHOMA CITY — Jayson Tatum scored 20 of his 27 points in the second half and the Boston Celtics rallied in the fourth quarter to beat the Oklahoma City Thunder 111-94 on Saturday night.
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.
"We feel good," Celtics guard Marcus Smart said. "We don't feel great. We don't feel like -- we're not complacent. We're not done. We're not satisfied. This is just a start for us."
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.
