Tyler Herro scored 18 and Gabe Vincent added 17 for the Heat, who outscored Boston 39-14 in the third quarter. Butler had 17 alone in the third, outscoring the Celtics by himself over those 12 minutes. Boston shot 2 for 15 in that third quarter. “We won three quarters other than that, but obviously that one is going to stand out,” Celtics coach Ime Udoka said. “We semi-bounced back in the fourth and started to play well again and matched their physicality, but 39-14 on 2-for-15 is tough to overcome.”
