BOSTON (AP) — Jaylen Brown scored 22 points, Kristaps Porzingis added 20 in his first game in more than a month and the Boston Celtics powered past the Dallas Mavericks 107-89 on Thursday night in Game 1 of the NBA Finals. Derrick White finished with 15 points for Boston, which led by 29 points in the first half and connected on 16 3-pointers in a powerful start to its quest for an 18th NBA title. Porzingis, who had been sidelined since April 29 with a strained right calf, came off the bench and provided an immediate spark, adding six rebounds and three blocks in 21 minutes. Six Celtics finished in double figures.
