BOSTON — Jaylen Brown scored 23 of his 36 points in the fourth quarter to help the Boston Celtics pull away for a 121-109 victory over the Minnesota Timberwolves on Friday night that halted their three-game losing streak.

Jayson Tatum had 30 points, eight rebounds and five assists, Derrick White scored 18, and Al Horford finished with 17 points for the Celtics.

Boston won for only the second time in seven games but moved back atop the NBA standings.

Anthony Edwards led the Timberwolves with 30 points, D’Angelo Russell scored 21 and Jaden McDaniels had 17. It was Minnesota’s second consecutive loss.

Boston point guard Marcus Smart had 10 assists, seven rebounds and six points after missing a game because of an illness, but center Robert Williams III was out sick.

Timberwolves center Rudy Gobert was held to eight points. He grabbed 12 rebounds in his second game after sitting out three because of a sprained left ankle.

Brown had a breakaway jam and followed that with a layup, giving the Celtics a 108-98 lead with 5 1/2 minutes to play.

After a free throw by Gobert, Brown nailed a 3-pointer from the left wing and Horford connected on one 31 seconds later, making it 114-99.

Horford’s buzzer-beating 3 from right in front of his team’s bench gave Boston an 88-86 edge entering the fourth.

LISTEN UP

Following a poor performance Wednesday when Boston fell behind by 30 in the opening half before a comeback bid against Indiana came up short, Celtics interim coach Joe Mazzulla issued a bit of a challenge.

“We have a choice to make: What team do we want to be?” he said after the game.

Boston responded with a solid start before Minnesota went on a 22-7 run.
