Towering Porzingis performance sparks Celtics

BOSTON — Kristaps Porzingis didn't want to make predictions about how his body would respond heading into the NBA Finals, after he spent more than a month on the sideline with a calf injury.

Just fine, it turned out.

Jaylen Brown scored 22 points and Porzingis made an immediate impact off the bench, adding 20 as the Boston Celtics powered past the Dallas Mavericks 107-89 for a Game 1 win on Thursday night.
