Celtics snap Thunder’s 12-game streak, deliver win of the year 119-109

The Boston Celtics returned to TD Garden on Wednesday night for what felt like more than just another regular season game. With the Oklahoma City Thunder riding a 12-game win streak and holding the top spot in the Western Conference, this had all the makings of a measuring stick matchup, the kind that quietly starts to feel a little like June if you let your mind wander.

Boston, meanwhile, entered the night looking to respond after a recent loss and continue finding its rhythm with a full rotation available. Against one of the league’s most complete teams on both ends of the floor, this was a good opportunity to see how their version of basketball holds up when the margin for error gets tight.

Thunder punch first, but Celtics answer

The Oklahoma City Thunder didn’t take long to seize control.

Behind early threes from Luguentz Dort and the steady pace of Shai Gilgeous-Alexander, OKC jumped out in front and immediately put Boston on its heels. Gilgeous-Alexander never looked rushed, picking his spots and operating comfortably as the Celtics largely let him work one-on-one to start.

On the other end, the Celtics couldn’t buy a basket. Sam Hauser got the looks you want, but missed them all, as Boston opened the game cold and out of sync. The Thunder’s defense didn’t help matters, constantly poking at dribbles and disrupting passing lanes, turning a few sloppy possessions into easy points the other way.

There were a few brief flashes. Jayson Tatum broke the drought in transition, Payton Pritchard knocked down a three off the bench, and Luka Garza brought some needed energy with an and-one late in the quarter. But nothing stuck, and Oklahoma City stayed in control throughout, closing the first on an 11–3 run to take a 31–20 lead into the second.

The Celtics looked like a completely different team to open the second quarter — and it started with Jayson Tatum.

After Boston opened the game just 3-for-12 on two-point attempts and shot under 30% through the first nine minutes, Tatum steadied everything. A quick three to start the quarter cut into the deficit, and from there, he began to dictate the pace of the game, both as a scorer and a facilitator. He attacked Holmgren off the dribble, found Queta for easy looks inside, and started reading the Thunder’s defensive pressure instead of reacting to it.

Gradually, Boston started to take control.

Their defense tightened up, clearly the result of intentional adjustments made by Joe Mazzulla. After allowing Oklahoma City to operate comfortably in the first quarter, the Celtics began forcing turnovers, getting back in transition, and making the Thunder work deeper into the shot clock. The energy shifted from scattered to controlled, and TD Garden responded accordingly.

Tatum was at the center of all of it.

During one stretch midway through the quarter, he scored or assisted on eight points in just over a minute, turning a double-digit deficit into a one-possession game. Jaylen Brown followed with a three off a Tatum drive-and-kick, and suddenly the Celtics had real momentum, forcing Mark Daigneault to call back-to-back timeouts.

Boston finally broke through late in the quarter.

An 8–0 run capped by a Payton Pritchard three gave the Celtics their first lead of the game, a moment that felt unlikely given how the night started. But just as quickly as the Garden erupted, Oklahoma City answered. Shai Gilgeous-Alexander returned and immediately settled things for the Thunder, getting to his spots with ease before Cason Wallace knocked down a three to erase the lead.

The final minute swung things back slightly in Oklahoma City’s favor.

A tough offensive foul on Tatum, a failed challenge on a goaltending call, and a last-second tip-in from Dort gave the Thunder a 53–49 lead heading into halftime. Still, after falling behind by as many as 13 and looking completely out of rhythm early, the Celtics had done enough to keep the game within reach — and more importantly, had started to look like themselves again.

Boston keeps it up in the third

Oklahoma City opened the second half looking ready to create separation, which has been their pattern all season. Shai Gilgeous-Alexander picked up right where he left off, scoring with ease and stretching the Thunder lead early, including a stretch where he hit seven of his first eight shots and knocked down three triples.

But this time, the Celtics didn’t let it get away.

Jaylen Brown set the tone with aggressive drives, getting downhill and forcing the issue after a quiet first half. Jayson Tatum continued to command attention as well, drawing multiple defenders and creating space for others, even as Oklahoma City stayed locked in on him defensively.

Boston started to find its rhythm through physicality and effort plays. Neemias Queta provided a spark inside, finishing through contact and delivering one of the loudest moments of the night with a powerful dunk over Chet Holmgren that brought TD Garden to life. Sam Hauser added a much-needed three after a prolonged cold stretch, helping stabilize the offense.

From there, the game settled into a possession-by-possession fight.

Boston leaned into its depth, with Baylor Scheierman providing an unexpected boost off the bench. He knocked down a pair of confident threes and held his own defensively, even forcing a turnover from Gilgeous-Alexander during a key stretch. Payton Pritchard followed with a deep three and a late floater, as the Celtics began to generate more consistent offense against a Thunder defense that had controlled the early stages of the game.

At the same time, the Celtics made subtle defensive adjustments. Gilgeous-Alexander still found his spots, finishing the third quarter with 26 points, but Boston began to make him work harder for them and limited easy paint touches around him.

The result was a steady shift in momentum.

After trailing for most of the night, the Celtics finally took control late in the quarter behind Brown’s continued pressure at the rim and timely shot-making from the supporting cast. Boston closed the third on a strong run, outscoring Oklahoma City 39–30 in the period to take an 88–83 lead into the fourth.

Celtics close the door in the fourth

Boston carried its second-half momentum into the fourth and quickly created breathing room.

Neemias Queta made an immediate impact, extending possessions on the glass and helping push the lead to its largest of the night early in the quarter. The ball movement followed. Queta found Sam Hauser in the corner for a wide-open three, and this time the shot dropped, stretching the lead as the Celtics began to settle into a rhythm offensively.

From there, Boston leaned heavily into the Jayson Tatum–center pick-and-roll.

Whether it was Queta or Luka Garza screening, the action consistently produced good looks. Tatum controlled the tempo, drew contact, and knocked down three free throws after getting Alex Caruso in the air. A few possessions later, he hit Garza on the roll for an easy finish, continuing to exploit Oklahoma City’s coverage.

The energy plays kept coming.

Baylor Scheierman delivered one of the biggest moments of the night with a putback dunk off a Tatum miss, crashing in from the corner and finishing above the rim as the crowd erupted. Not long after, he knocked down a step-back three from a similar spot, showing confidence and giving Boston a jolt on both ends.

Jaylen Brown built on that momentum with consistent pressure at the rim. He attacked closeouts, got to the line, and converted an and-one after getting Shai Gilgeous-Alexander off his feet, drawing loud MVP chants as the Celtics extended their advantage.

Even as Gilgeous-Alexander continued to produce offensively, Boston maintained control.

The Celtics forced misses, limited second chances, and got timely shot-making from Payton Pritchard, whose three pushed the lead to 14 midway through the quarter. At that point, Boston had found a steady rhythm on both ends, with its offense generating clean looks and its defense doing enough to keep Oklahoma City from stringing together stops.

The Thunder made one final push.

A quick run trimmed the lead back into single digits, fueled by perimeter shot-making and trips to the free-throw line, as Oklahoma City continued to benefit from a favorable whistle throughout the night. But Boston responded with composure, continuing to attack the paint and get to the line, with Brown staying aggressive as the game moved inside the final few minutes.

Boston closed it out, 119–109, for what stands as its biggest win of the season.

The Celtics had dropped five of their last six coming in, including three straight against Oklahoma City, adding weight to a matchup that already carried plenty of it. Against one of the league’s hottest teams, they responded to a loss against Minnesota with their most complete performance in weeks, overcoming a slow start and taking control in the second half.

They’ll look to carry that momentum into Friday night, when they host the Atlanta Hawks at TD Garden at 7:30pm ET.
