Jae Crowder finally slammed the door on the comeback with a corner 3 that gave Utah a 117-109 lead with 47.7 seconds left.
Utah coach Quin Snyder thought his team turned a corner by hanging tough down the stretch against the Celtics.
“Our team has not been able to handle successes during games at times,” Snyder said. “We’ve lost focus sometimes when we’ve hit shots. Teams are going to come back on you, but you can’t make it easy on them.”
Donovan Mitchell scored 21 points for Utah. Crowder had 20, and Gobert finished with 17 points and 15 rebounds. The Jazz won their second straight home game and second in a row overall.
“We all have picked it up, picked up our energy defensively, picked our focus up,” Mitchell said. “We’ve been having great practices, but we just didn’t put it into the games. I think over the past couple of games, we’ve done that.”
Terry Rozier scored a season-high 22 points, making his first start in place of Irving, and Jayson Tatum added 21 for the Celtics.
Boston lost for the third time in four games after allowing Utah to shoot a season-high 56 percent from the field.
“As good as we were defensively in the first nine games, I don’t think we’ve been as good the last three,” coach Brad Stevens said. “I thought we actually did an OK job on the initial drives in isolation, but we didn’t get rebounds in a lot of cases. Our pick-and-roll defense, we just have to really shore it up.”
