The Boston Celtics scored 53 points — their biggest-scoring first quarter ever — in the opening 12 minutes of their game against the Miami Heat on Wednesday night.
Boston’s barrage is tied for the second-highest-scoring first quarter in NBA regular-season history. Golden State had a 55-point opening quarter at Portland on April 9, 2023, and Miami had a 53-point opening quarter against Charlotte on Nov. 7.
