NEW YORK — Jayson Tatum scored 34 points, setting a new franchise record with his 40th 30-point game this season, and the Boston Celtics rolled to a 120-95 win over the Indiana Pacers on Friday night.

Tatum passed Hall of Famer Larry Bird, who had 39 30-point games during the 1987-88 season.

Jaylen Brown added 27 points and seven rebounds, and Derrick White finished with 22 points and nine assists.

The Celtics have won four out of five and improved to 27-9 at home this season.

Five of Boston’s remaining eight games will be at TD Garden as they try to catch Milwaukee in the race for the Eastern Conference’s top playoff seed. The Bucks entered the day with a 2 1/2-game edge in the standings. The Celtics had a half-game lead over third-place Philadelphia.

Pacers All-Star point guard Tyrese Haliburton had 20 points, nine assists and six rebounds in his first game back from a six-game absence with a combination of a bruised left knee and sprained right ankle. Myles Turner added 20 points and six rebounds.

Indiana entered the game 1 1/2 games behind the Chicago Bulls for 10th place in the East and the final spot in the play-in tournament.

Brown and Tatum combined for 12 straight points during a 17-5 run in the third quarter to help the Celtics take a 77-62 lead.

It included them working together to score five straight points during an 8-second sequence. First, Tatum dropped in a layup off a Marcus Smart steal. Then, Tatum came up with a loose ball and fed Brown for a 26-footer.

The Celtics outscored the Pacers 32-21 in the period and started the fourth on a 14-2 run, taking as much as a 29-point advantage.
