Kyrie Irving had 17 points and seven assists and Jaylen Brown scored 18 as Boston beat the Chicago Bulls 111-82 on Wednesday night.
The Celtics were back home for the first time since going 1-4 on a long trip that wrapped up with back-to-back losses in Utah and Portland. After a slow start through the first quarter, Boston started pulling away from the Bulls in the second quarter and never let up.

Jabari Parker scored 14 in the first quarter for the Bulls, but was shut out the rest of the way.
Shaquille Harrison led Chicago with 16 points. Zach LaVine had 10 points and nine assists, and Wendell Carter Jr. added 11 points and seven rebounds.
The Celtics dominated the second quarter, holding Chicago to 11 points on five field goals, and continued to pull away in the second half. They held a 22-point lead entering the fourth quarter and emptied their bench. The reserves stretched the advantage to 33 before it was over.
Terry Rozier had 12 points for Boston, and Aaron Baynes finished with nine points and 11 rebounds.
After going 9 for 23 in the first quarter, the Celtics outscored Chicago 32-11 in the second and forced the Bulls into seven turnovers.
Rozier's free throw after a technical foul on LaVine broke a 28-all tie and started Boston on a 12-0 run. The Celtics shut out the Bulls for 5:14 while pulling ahead 42-30, then closed the period on a 9-2 spurt for a 51-35 halftime lead.
Baynes opened the fourth quarter for Boston with a 3-pointer and added a three-point play with 9:46 remaining to extend the margin to 87-64.
Hayward followed with a jumper, then converted another three-point play as the Celtics opened a 92-64 bulge with 9:32 left.
