Jaylen Brown had 29 points and 12 rebounds, and the Boston Celtics capitalized on a woeful shooting performance by the Atlanta Hawks to hold on for 112-99 victory in Game 1 of the Eastern Conference first-round matchup on Saturday.

Jayson Tatum scored 25 points, 21 in the first half. Derrick White finished with 25 points and 11 rebounds for Boston, which hosts Game 2 on Tuesday.

The No. 2-seeded Celtics led by as many as 32 points, pouncing on an Atlanta team that missed its first 10 3-point attempts and shot 5 of 29 from beyond the arc for the game.

Atlanta used a 32-12 run to cut the deficit to 96-84 on a three-point play by Bogdan Bogdanovic early in the fourth.

The Celtics got the lead back up to 107-87. It was 110-97 with less than two minutes to play when Atlanta’s De’Andre Hunter got free on fast break. But his layup attempt was blocked from behind by Marcus Smart.

Dejounte Murray led the Hawks with 24 points, eight rebounds and six assists. Trae Young added 16 points.

Despite Atlanta’s late push, the Celtics sizzled from all points on the floor, connecting on 13 3 pointers.

After dropping in his third 3-pointer in the closing seconds of the first half, Tatum spread his arms out wide as he backed down the court to a huge ovation from the TD Garden crowd.

A big part of Boston’s game plan coming in was neutralizing Young and Murray, Atlanta’s top two scorers. The Celtics did that and a lot more in the first three quarters.

Young, who was 10th in the NBA in scoring, missed his first six shots beyond the arc and was 5 of 18 from the field. Murray was 10 of 25 from the floor.

In a move to match Atlanta’s speed, Boston went small at the outset, White instead of big man Robert Williams in a lineup alongside Al Horford, Tatum, Brown and Smart.

It seemed to neutralize the Hawks’ attack.

Young had an especially rough start. He had a pass the first possession of the game stolen by Brown and had his first field goal attempt blocked by White on the way to missing his first six shots.

Atlanta coach Quin Snyder said before the game a point of emphasis would be not to turn down open 3s or be deterred by misses.

That wish was tested as Hawks shot 9 of 25 from the field in the opening period and 0 for 9 from beyond the arc as the Celtics took to a 29-19 lead.

With Young struggling, Boston found a rhythm early in the second, starting the quarter on a 25-10 run to increase their lead to 25.
