DALLAS — Jayson Tatum scored 31 points, Jaylen Brown had 30 and the Boston Celtics held off a furious Dallas rally to reach the brink of a record 18th championship with a 106-99 victory over the Mavericks on Wednesday night for a 3-0 lead in the NBA Finals.
Brown finished with eight rebounds and eight assists as the Celtics extended their franchise record with a 10th consecutive playoff victory and moved to 7-0 on the road this postseason.
