Celtics’ exceptional offense burns Heat.

MIAMI — On Wednesday evening, the Boston Celtics achieved an unprecedented first quarter in their illustrious franchise history, accumulating 53 points within the initial 12 minutes en route to a 147-129 win against the Miami Heat.

This represented the second-highest point total for an opening period in the NBA’s regular season record. The Golden State Warriors previously recorded 55 points in their first quarter against Portland on April 9, 2023, while Miami itself posted 53 points in an initial quarter facing Charlotte on November 7.

Celtics standout Jaylen Brown remarked, “Penetrating the lane, driving to the hoop, and completing plays. I believe that served as the primary driving force.”

The 147 points accumulated by Boston equaled their second-highest total ever achieved in an away fixture for the organization. Furthermore, this marked the highest number of points the Heat have ever conceded on their home court.

Celtics head coach Joe Mazzulla commented, “I felt our performance was quite effective. Occasionally, when execution is strong, you continuously secure favorable shooting opportunities. It simply unfolds naturally. Typically, in such instances, when momentum builds, players might attempt ill-advised shots. We avoided that. We persisted in seeking out optimal chances, the subsequent finest option, and I believe that helped sustain our impetus somewhat.”

Boston held a 53-33 advantage upon the conclusion of the quarter, having converted 20 of 28 attempts from the floor and 11 of 15 attempts from beyond the arc.

The 53 points scored in the initial quarter represented the Celtics’ second-highest single-quarter output; they previously amassed 54 points in the final quarter of a contest versus the San Diego Clippers on February 25, 1970. Moreover, this was the highest point total Miami has ever surrendered in any quarter; the Heat conceded 50 points in the fourth quarter during a match in Seattle on January 5, 1990.

Sam Hauser contributed 17 points, achieving a perfect 5-for-5 record from three-point range, having participated for the entire 12 minutes of the opening frame. Brown personally notched 20 points in that period, marking the ninth time in his career, encompassing postseason games, he has reached a 20-point quarter.

Heat coach Erik Spoelstra stated, “It might seem unbelievable, yet this situation deviates from the other matches we’re discussing. Our players were intensely focused and contending. Boston displayed an extraordinary caliber of shot execution at the game’s commencement.”

Brown ultimately recorded 43 points, and Jayson Tatum achieved a triple-double with 28 points, 18 rebounds, and 11 assists — his inaugural one this season, following a significant absence due to recovery from the Achilles tendon rupture sustained in the previous season’s playoffs.

Across his last three appearances, Tatum has accumulated 83 points, 35 rebounds, and 24 assists. The most recent Celtics individual to register such statistics over a three-game stretch was Larry Bird, back in April of 1990.

Tatum commented, “The performance showcased exceptional shot conversion by both teams.”
