The energy at TD Garden was electric on March 25, 2026, as the Boston Celtics welcomed the Oklahoma City Thunder in a clash of NBA titans. With both teams finally at full strength, fans packed the arena, eager to see if the Celtics could topple the defending champions and keep their own championship dreams alive. The stakes? Bragging rights between the last two NBA champions, playoff positioning, and the end of a remarkable 12-game Thunder winning streak.
Boston entered the contest with a 47-24 record, while Oklahoma City boasted the league’s best at 57-15. The anticipation was palpable—not just for the outcome, but also for the return of key stars. For the first time this season, the Celtics started Derrick White, Jaylen Brown, and Jayson Tatum together in a marquee matchup. The Thunder, meanwhile, had all their main weapons healthy, including Jalen Williams in only his second game back from a hamstring injury and Isaiah Hartenstein returning from a bruised left calf.
Early on, it looked like the Thunder might steamroll the Celtics. Oklahoma City came out firing, building a 13-point lead in the first quarter and finishing the opening frame up 31-20. Boston struggled mightily from the field, shooting just 29.2% (7-of-24) in the first 12 minutes. Sam Hauser, left open repeatedly, couldn’t find his rhythm, making just one of his first six shots and missing four of five from deep. Only Luka Garza managed multiple buckets for Boston in those early moments.
But the Celtics didn’t fold. Instead, they regrouped in the second quarter, led by the trio of Tatum, Brown, and White. The three combined for 23 second-quarter points, fueling a 29-15 run that briefly gave Boston a 49-46 lead after a Payton Pritchard three-pointer capped an 11-0 surge. Still, the Thunder answered with a seven-point burst to close the half, taking a 53-49 advantage into the locker room. Eleven different Thunder players had scored by halftime, showing the depth of the Western Conference leaders.
Coming out of the break, the Celtics looked like a different team. Jaylen Brown, who has been in the thick of the NBA MVP conversation, put on a show worthy of the chants echoing through the Garden. Brown poured in 14 of his 31 points in the third quarter alone, making three of four field goals and hitting eight of nine free throws. According to the Associated Press, "Brown’s big quarter helped the Celtics take an 88-83 lead into the fourth." The Celtics outscored Oklahoma City 39-30 in the third, seizing the momentum and igniting the home crowd.
Jayson Tatum, still working his way back from a ruptured Achilles, delivered his best performance since returning from injury. In his ninth game back and playing a season-high 35 minutes, Tatum flirted with a triple-double: 19 points, 12 rebounds, and seven assists. "Tatum recovered from back-to-back rocky performances to add 19 points and 12 rebounds while also contributing seven assists as Boston earned a split in the two regular-season matchups between the past two NBA champs," reported the AP.
The Celtics’ supporting cast also stepped up. Payton Pritchard was a spark off the bench, knocking down four of six from beyond the arc for 14 points. Baylor Scheierman chipped in with 11 points, including five in the final quarter to help seal the comeback. Boston’s defense tightened, limiting the Thunder to just 12-of-37 shooting from three-point range and dominating second-chance points 19-2.
Still, the Thunder didn’t go quietly. Shai Gilgeous-Alexander, last season’s NBA MVP and the league’s leading scorer, was spectacular. He tallied 33 points on a hyper-efficient 10-of-12 shooting and nailed 10 of 12 free throws, while also dishing out eight assists. Lu Dort provided a boost with 14 points, hitting four threes, and Jalen Williams, continuing his return from injury, added seven points. The Thunder clawed back to within six points with just 1:30 left, making it 115-109 after a Gilgeous-Alexander layup.
But Boston had the answer each time. With the game hanging in the balance, Brown hit a tough jumper to push the lead to 117-109 with 47.3 seconds remaining. Derrick White calmly sank two free throws to close out the scoring, and the Celtics’ defense did the rest. When the final buzzer sounded, Boston had completed a 119-109 comeback victory, snapping Oklahoma City’s 12-game winning streak and improving their own record to 48-24.
It was a statement win for the Celtics, not just because of the opponent, but because of the resilience they showed after a rocky start. The Celtics outscored the Thunder by 19 points in the second-chance category and overcame a double-digit deficit against the league’s best team. According to Field Level Media, "The Celtics tied the game at 71-all on two Brown free throws and took a 74-73 lead on a Baylor Scheierman 3-pointer with 5:07 left in the third quarter." From there, Boston never looked back.
The game also marked a rare late-season meeting between elite teams still fine-tuning their lineups for the playoffs. The first matchup between these teams, just two weeks prior in Oklahoma City, saw the Thunder edge the Celtics by two points—though both teams were missing key players. This time, with both squads at full strength, the Celtics showed they could go toe-to-toe with the league’s elite.
Looking ahead, the Thunder will regroup at home against the Chicago Bulls as they begin their longest homestand of the season. For Boston, the win provides a major confidence boost as they prepare to host the Atlanta Hawks on Friday. With the playoffs looming, both teams know there’s still plenty to iron out, but this showdown offered a tantalizing preview of what could be a future playoff classic.
As fans filed out of TD Garden, the buzz was unmistakable. The Celtics proved they can compete with anyone, and with their stars healthy and clicking, Banner No. 19 might not be just a dream after all. The Thunder, meanwhile, leave Boston with plenty of lessons—and perhaps a little extra motivation for the next meeting. One thing’s for sure: NBA fans everywhere will be watching.
