ATLANTA — Jayson Tatum led a balanced offense by scoring 11 of his 34 points in the fourth quarter, and the Boston Celtics overcame Atlanta’s fourth-quarter comeback bid, beating the Hawks 134-125 on Saturday night.

The Celtics opened a six-game trip by having six players score in double figures. Jaylen Brown finished with 24 points. Tatum added 14 rebounds.

Trae Young had 35 points and 13 assists for Atlanta, which could not maintain momentum following back-to-back wins at Washington. The Hawks remain eighth in the Eastern Conference standings.

With 1:25 remaining and Boston leading 129-121, Young and Marcus Smart had to be separated after the two were entangled and fell to the court under the Celtics’ basket. Smart was called for an initial foul before a lengthy review by the officials, who called both players for technical fouls and ejected Smart.

Young made two free throws to cut the deficit to six points.

Boston led by 16 at 60-44, but the Hawks rallied in the final quarter. Clint Capela’s tip-in cut Boston’s lead to 108-103 with 8:06 remaining. Boston still led by only five points before Smart’s 3-pointer stretched the advantage to 117-109.

Young’s 3-pointer again pulled Atlanta within 119-114 before Al Horford answered with a 3 for Boston and Tatum’s layup extended the advantage to 10 points.

The Hawks led 40-39 early in the second quarter before Malcolm Brogdon’s 3-pointer started a 21-4 run for the Celtics. Sam Hauser sank two 3s during the stretch.
