The Celtics (35-19) swept the season series with Utah after beating the Jazz 115-104 on Jan. 3.
Gordon Hayward scored 25 points and George Hill added 22 to lead the Jazz, who could not overcome poor shooting and struggled to get defensive stops during critical stretches.
Boston, which never trailed, stayed a step ahead of the Jazz throughout the first quarter behind hot shooting. The Celtics scored on their first three possessions, culminating in a dunk from Amir Johnson, to set the tone for a half in which they shot 24 of 36 (66.7 percent) from the field.
The Jazz could not stop Boston from attacking the paint early and finding a quick rhythm both inside and outside. Olynyk gave the Celtics their first double-digit lead at 33-23 when he finished off the quarter with a 3-pointer and a buzzer-beating layup.
The Jazz whittled the deficit down to 37-30 on a dunk from Derrick Favors early in the second quarter. Boston answered with a 10-0 run to blow the game open before halftime. Green kickstarted the run with three straight baskets. Thomas finished it off with a pair of free throws to put the Celtics up 47-30 with 5:28 remaining in the half.
Utah pulled within single digits again during the third quarter. The Jazz trimmed their deficit to 64-56 on a reverse dunk from Rudy Gobert. Olynyk quickly countered with a 3-pointer and then James Young followed with a running layup and another three to push the Celtics’ lead to 72-58.
Boston extended its lead to 85-65 after opening the fourth quarter with an 8-0 run. Thomas fueled the run by feeding Horford for a 3-pointer and then burying one of his own on the ensuing possession.
The Jazz made one final rally, cutting the Celtics’ lead to 108-102 on a corner 3 from Hayward with 22 seconds left. Horford and Marcus Smart each hit a pair of free throws in the final seconds to seal the win.
