Millsap scored 14 points during a 24-5 run that bridged the end of the second quarter and the start of the third and put Atlanta ahead 73-47 with 8:24 left in the quarter. The margin grew to 96-64 heading into the fourth and Atlanta beat Milwaukee for the eighth time in their last nine games.
Reserve Louis Williams had 18 points for the Hawks.
Shelvin Mack scored nine points starting at point guard for Jeff Teague, who sprained his left ankle during the Hawks’ 105-79 loss to San Antonio on Friday. Teague hurt his ankle when he landed on Tim Duncan’s foot late in the second quarter.
That game marked Atlanta’s season-low in points.
Williams alternated with Mack running the offense throughout the game Saturday.
Brandon Knight scored 27 points for the Bucks, who lost for the 11th time in their last 12 games. Ersan Ilyasova and Khris Middleton added 11 apiece.
Atlanta regained its shooting touch from 3-point range, making 13 of 24 3s after going only 2-of-13 against San Antonio. Williams made two of the Hawks’ four 3-pointers during a 16-9 run late in the first quarter and Mike Scott’s 3 capped an 11-3 surge just before the half for a 60-45 lead.
DeMarre Carroll scored 12 points in his return to the starting lineup after missing the game against the Spurs with a left hamstring strain. Scott finished with 14 points, Kyle Korver 12 and Elton Brand 10 as the Hawks beat Milwaukee for the fifth consecutive game, the first time they’ve done that since a taking six straight in 1996 and ’97.
Atlanta swept the four-game series last season.
Giannis Antetokounmpo, playing with a sore back, scored five points in the first half for NBA-worst Milwaukee (8-35).
Rookie Pero Antic (stress fracture in right ankle) and Carroll already were out before Teague’s injury left the Hawks with just 10 players on Friday. Antic had replaced starting center Al Horford, out for the season with a torn right pectoral.
NOTES: Korver was 3-of-4 from beyond the arc, extending his NBA record to 112 consecutive games with a 3-pointer. … Bucks coach Larry Drew faced the Hawks, the team he coached last season before being dismissed, for the first time this season. “I wish it were under better circumstances,” he said. … Referee Josh Tiven called a technical on the Bucks’ John Henson for hanging on the net in the first quarter. … Atlanta was 8-of-16 from 3-point range in the first half.
