Boston Celtics Beat Oklahoma City Thunder In Possible NBA Finals Preview

If you wandered into TD Garden on Wednesday night, you could be forgiven for checking your calendar to make sure it wasn’t suddenly mid-June. The energy in the building was electric, carrying that distinct, nerve-wracking buzz usually reserved for the NBA Finals.

And why wouldn’t it? The Boston Celtics and the Oklahoma City Thunder entered the night as the betting favorites to meet with the Larry O’Brien trophy on the line. What they delivered was an absolute heavyweight bout, complete with wild momentum swings, absurd individual performances, and the Celtics ultimately snapping Oklahoma City’s daunting 12-game winning streak in a 119-109 victory.

If this is the cinematic trailer for the 2026 NBA Finals, basketball fans should probably go ahead and buy their tickets right now.

Surriving An Early TD Garden Hangover

Revenge was undeniably on the menu for Boston. Just two weeks ago, they dropped a dramatic two-point heartbreaker in Oklahoma City. But instead of coming out breathing fire, the Celtics started the game looking like a team that had mutually agreed to hit the snooze button.

The opening quarter was, frankly, a bit of a mess. Boston’s offense somehow resulted in Sam Hauser taking six of the team’s first ten shots. Hauser is a reliable marksman, but on Wednesday night, he was shooting like the rim was actively moving away from him. He missed four of his first five attempts from deep, allowing the Thunder to casually jog out to an 11-3 lead.

Jayson Tatum didn’t help matters early on, either, coughing up back-to-back turnovers in a sluggish first period. But championship-caliber teams don’t panic when the alarm bells go off; they just find another way to win.

The Celtics Dominate the Dirty Work

When the beautiful, flowing offense isn’t working, you have to roll up your sleeves and get to work in the mud. That is exactly how the Celtics clawed their way back into this game.

Tatum, fresh off a frustrating outing against Minnesota, flipped a switch in the second quarter. He shook off the early rust to put together a quintessential gritty performance, finishing with 19 points, 12 rebounds, 7 assists, 3 steals, and a massive block. He was everywhere.

But the real story of the night was the hustle stats. Boston absolutely bullied Oklahoma City on the glass. The Celtics finished the game with a downright comical 19-2 advantage in second-chance points. You simply cannot expect to beat a team of Boston’s caliber on their home floor if you are handing them 19 free points off rebounds.

Surviving a Robotic Shai Gilgeous-Alexander

It feels wrong to talk about this game without tipping a cap to last season’s MVP, Shai Gilgeous-Alexander. SGA played like a guy who hacked his own NBA 2K sliders before tip-off.

He finished with 33 points on a mind-numbing 10-for-12 from the floor and 10-for-12 from the free-throw line. It was a near-flawless offensive masterclass. Every time the crowd started to get loud, SGA would casually glide into the lane, contort his body in defiance of human anatomy, and drop in a bucket. Yet, despite his robotic efficiency, it wasn’t enough to withstand Boston’s counter-punch.

Jaylen Brown Brings the Emotion

If SGA was the cold, calculating machine for the Thunder, Jaylen Brown was the roaring heartbeat for the Celtics.

After missing his first six shots of the game, Brown decided he’d simply had enough in the third quarter. He exploded for 14 of his game-high 31 points in that pivotal frame. Every time he stepped to the foul line, the TD Garden faithful showered him with MVP chants.

The undisputed highlight of the night, however, came late in the third. Brown isolated against Isaiah Joe, spun past defensive ace Alex Caruso like he was standing in wet cement, and violently threw down a one-handed poster slam over Jaylin Williams. The arena lost its collective mind. It was the kind of emotional, tone-setting play that demoralizes an opponent and reminds the rest of the league exactly who runs the Eastern Conference.

The Celtics managed to stretch their lead to as many as 14 points in the fourth quarter. And while Oklahoma City made a frantic push to get within six in the dying moments, a clutch layup by Brown and ice-cold free throws by Derrick White slammed the door shut.

If this Wednesday night thriller truly was a preview of what’s to come this summer, we are all in for one heck of a basketball series.
