Al Horford and Jaylen Brown combined to do the bulk of the damage and the Celtics won the 3rd quarter 34-16, but Houston opened up the fourth on a 10-4 run. The C’s, who hadn’t made wholesale substitutions yet, held strong and made one final push into garbage time. Aaron Nesmith came into the game with Tatum still on the floor and hit back-to-back 3-pointers to put it away.
