Gallinari broke the mark of nine 3-pointers by Steve Smith in a 1997 game against Seattle. The Hawks also eclipsed the overall team record by going 23 of 42 beyond beyond the arc.
Trae Young played like an All-Star, adding 33 points as the Hawks built a 27-point lead in the first half and were never threatened by a lackluster Celtics team that lost its third in a row.
Gallinari, one of the biggest free agents signed by the Hawks in an offseason spending spree, equaled the best scoring half of his career with 24 points over the first two quarters. He finished 10 of 12 from 3-point range and 13 of 16 overall.
The Hawks led 72-49 at halftime and maintained a comfortable margin the rest of the way.
It was much-needed rebound for Young and the Hawks, who lost 112-111 at Cleveland the previous night on a last-second shot — just hours after Atlanta’s star guard learned he had been passed over for a spot in the March 7 All-Star Game to be held on his home court.
In Indiana, Stephen Curry scored 24 points, Draymond Green fell just short of a triple-double and the weary Golden State Warriors beat the Indiana Pacers 111-107.
Green had 12 points, 11 rebounds, nine assists and three steals. The Warriors took control with a late 6-0 run to seal their second straight victory on a four-game trip.
Zion Williamson scored 32 points in his first game since being named a first-time All-Star, and the New Orleans Pelicans beat the Detroit Pistons 128-118.
Highlighting his performance with quick dribbling spin moves in the paint, or with thunderous one-handed dunks on cuts down the lane, Williamson made 13 of his 18 shots.
It’s the eighth time this season he finished with 30 points or more. (AP)
