Zach LaVine scored 22 points, DeMar DeRozan had 28 and Chicago stopped Boston's nine-game win streak, beating the Celtics 121-107 on Monday night.

Patrick Williams scored a season-high 17, and the Bulls made it look rather easy against a team that's 13-4. They led by 13 at halftime, got it up to 21 in the third quarter and withstood a push to come away with the win after dropping four straight and five of six.

LaVine was coming off what might have been the worst performance of his career. The two-time All-Star was 1 of 14 with four points against Orlando on Friday and got benched for the final 3:43.

Against Boston, he was 8 of 20 from the field, but made five 3-pointers. He also scored nine in the fourth quarter.

DeRozan, who scored 41 in the previous game, had eight in a span of just over a minute late in the third. He also spun and fed Alex Caruso for a reverse layup that made it 116-101 with just under three minutes left in the game.

Jayson Tatum led Boston with 28 points. Jaylen Brown scored 25, and Malcolm Brogdon finished with 23 points, nailing 5 of 6 3-pointers.

The Bulls visit Milwaukee on Wednesday.
