BOSTON — The Celtics didn’t need a knockout punch. They needed control, and they found it in the details.
Boston (45-23) beat Phoenix (39-29) 120-112 on Monday night at TD Garden, leaning on clean offensive organization and a consistent scoring profile across four quarters. The Celtics finished with 31 assists — a telling number in a game that repeatedly swung on execution — while the Suns totaled 26.
How the game tilted
Phoenix arrived in form (LLWWW) and came out sharp, taking the first quarter 32-31 behind early pace and shot creation. But Boston’s response in the second was the hinge point: the Celtics won the period 34-29 to take a 65-61 lead into halftime.
From there, the game settled into a possession-by-possession grind. Boston slightly extended the margin in the third (26-25) and matched Phoenix in the fourth with another small but meaningful edge (29-26). The result was a wire-to-wire second-half posture: Phoenix was close enough to threaten, but Boston was organized enough to keep the Suns from flipping the script.
Ball movement was the separator
In a matchup without provided shooting splits or rebounding totals, the clearest statistical separator was playmaking. Boston’s 31 assists underscored a night where the Celtics repeatedly turned initial advantages into quality looks — the kind of process that travels from quarter to quarter and makes runs harder to sustain against them.
Phoenix’s 26 assists reflects a functional offense, but Boston’s extra layer of connectivity showed up most in the second quarter and late-game management. When the Suns needed a sequence to erase the gap, Boston consistently found the next pass and the next decision.
Quarter-by-quarter snapshot
First quarter: Suns strike first
Phoenix’s 32 points put immediate pressure on Boston, but the Celtics stayed attached at 31, keeping the game from turning into a track meet.
Second quarter: Boston builds the cushion
The Celtics’ 34-29 quarter created the night’s most important swing, turning a one-point deficit into a four-point halftime lead.
Third quarter: Celtics keep the pressure on
Boston’s 26-25 edge wasn’t loud, but it mattered — the Celtics kept Phoenix from reclaiming momentum while nudging the lead forward.
Fourth quarter: Execution closes it
Phoenix had chances, but Boston’s 29 points in the fourth ensured the Suns never got the clean window they needed. The Celtics won the period 29-26 to seal the 120-112 finish.
What it means going forward
For Boston, this was a mature win: not their flashiest quarter-to-quarter performance, but a steady, offense-driven control game that fit the profile of a 45-23 team. The Celtics’ current stretch (WWLLW) continues to look like a group that can win in different textures — including nights when the opponent is capable of putting real scoring pressure on the scoreboard.
For Phoenix, the loss snaps some of the momentum from their recent run (LLWWW). The Suns proved they can score with Boston and win a quarter on the road, but the second-quarter dip and the late-game margins showed how thin the line is against elite teams when the opponent is generating offense through high-level passing.
