Boston didn’t win this one with a runaway stretch — it won it with control in the moments that decide games. The Celtics finished the night with a decisive fourth quarter, outscoring the Memphis Grizzlies 33-24 to secure a 117-112 win Saturday at FedExForum.

The result keeps Boston rolling at 47-23 (WWWWL) and drops Memphis to 24-45 (LWLLL), another close loss in a season that’s offered too few clean finishes.

How the game swung

Through three quarters, Memphis looked capable of flipping the script. After trailing by one at the half (55-54), the Grizzlies delivered their best frame in the third, winning it 34-29 to take a 88-84 lead into the fourth.

Boston’s response was immediate and clinical. The Celtics’ 33-point fourth quarter erased the deficit and created separation late, while Memphis’ offense stalled to 24 points in the period — the difference in a five-point game.

Playmaking profile: Celtics win the finish, Grizzlies win the assist count

Memphis generated more assisted offense overall, finishing with 24 assists to Boston’s 19. But the assist edge didn’t translate into fourth-quarter control, where Boston’s shot-making and late-game execution swung the outcome.

What it means going forward

For Boston, this was a professional road win: absorb a third-quarter surge, then lock in late and take the game with a dominant fourth. At 47-23, the Celtics continue to stack results and show they can win without needing a perfect 48 minutes.

For Memphis, the loss reinforces the current trend. The Grizzlies played well enough for three quarters — even winning the middle two frames — but couldn’t sustain it when the game tightened. At 24-45, the margin for error is gone, and closing quarters remain the clearest pressure point.
