BOSTON — The Celtics didn’t waste time letting this one breathe. Boston detonated for 36 points in the first quarter, built immediate separation, and carried that control all the way to a 120-99 win over the Golden State Warriors on March 18, 2026 at TD Garden.

The result pushed Boston to 46-23, a steadier snapshot than its recent WWWLL form suggested. Golden State, already sliding at LWLLL, fell to 33-36 after another night spent chasing the game’s tempo instead of dictating it.

The game swung early — and stayed there

Boston’s opening quarter was the defining stretch: 36-23, a +13 punch that set the scoreboard and the tone. Golden State stabilized in the second, matching Boston 27-27, but it didn’t change the geometry of the game — the Warriors still needed a run, and Boston never offered one.

Coming out of halftime, the Celtics kept the pressure on with a 26-23 third quarter, then turned the fourth into a finish line: 31-26 to close out a comfortable 21-point win.

Ball movement: different numbers, same outcome

Golden State actually finished with more assists (26) than Boston (22), but the Celtics’ advantage was built on scoreboard leverage — the early lead allowed Boston to play from strength, manage possessions, and keep Golden State from generating the kind of momentum that turns playmaking into points in bunches.

What it means going forward

For Boston, the formula was clean: win the first quarter, control the middle, finish with force. At 46-23, the Celtics continue to stack wins in a tight late-season calendar, and this was the kind of wire-to-wire performance that travels into the postseason.

For Golden State, the margin matters as much as the loss. Falling to 33-36 with the recent LWLLL form still intact, the Warriors need answers quickly — not just in execution, but in the ability to survive early storms against top-tier opponents.
