Jaylen Brown scored 29 points, Jayson Tatum had 18 points and 11 rebounds and Payton Pritchard scored 25 points off the bench as the Boston Celtics defeated the Miami Heat 108-89 on Monday night. Derrick White added 19 points as the reigning NBA champions won for the eighth time in nine games. Jaime Jaquez Jr. had 19 points and 10 rebounds and Tyler Herro scored 19 for Miami. Herro was 2-for-10 from 3-point range and the Heat shot 23% from long range and 36% from the field. Both teams were without key players for the second time in a row after Sunday’s defeat. Miami played without Jimmy Butler, who missed five of the first 19 games with a knee injury. The Celtics were without Jrue Holiday, Al Horford and Kristaps Porzingis. Miami scored the first seven points and then went cold as the Celtics squandered 17 of the next 19 points to take the lead. Boston built a double-digit lead early in the second quarter and went up by 20 in the third. TakeawaysHeat: Keshad Johnson made his NBA debut and scored two points in seven minutes. Celtics: Haven’t lost all games in a row this season. Key MomentPritchard, who hit two halfcourt buzzer-beaters in the NBA Finals, beat the buzzer in the third quarter on Monday night when he dribbled down the lane, evading defender Pelle Larsson and a left-handed shot off the backboard gave Boston a 22-point lead – the largest lead in the game up to that point. Key Stat: Pritchard became the first NBA player this season to score 20 or more bench points in four straight games. He is the first Celtic to achieve this since Isaiah Thomas in 2015. Next up, both teams are at home on Wednesday night, with the Celtics hosting Detroit and the Heat hosting the Lakers.
