Marvin Williams finished with 16 points and Jeremy Lin scored 15 for Charlotte, which trailed the entire game. The Hornets were trying to be the first Charlotte team since 1996-97 to win eight games in February.
They pulled within two with 7 minutes left but couldn’t rally after scoring a season-worst nine points in the first quarter.
The Hawks ended a disappointing five-game home stand with two straight wins to pull two games ahead of third-place Charlotte in the Southeast Division.
Atlanta led by 10 in the first on Bazemore’s uncontested dunk. With his team down by 12, Hornets coach Steve Clifford called timeout at the 3:59 mark of the first, but Charlotte missed its next six shots and was 1 for 19 from the field before Lin hit a 3.
Kemba Walker, who was leading the Eastern Conference with a 24.1 points per game scoring average this month, finished with nine points on 3 for 15 shooting.
Atlanta took its first 20-point lead on Mike Scott‘s layup early in the second and was up a game-high 24 on Millsap’s layup at the 7:53 mark.
Charlotte pulled within five early in the third on Courtney Lee‘s layup, but the Hornets went cold again and trailed 60-43 when Jeff Teague hit a 3 at 5:16.
Their last surge came in the fourth. Lin scored five unanswered points, Frank Kaminsky hit a floater on the baseline, and Jeremy Lamb scored to make it 70-68 with 7:22 remaining, but Charlotte never got any closer.
Horford hit a straightaway 3 and a layup to put the Hawks up by 13 with 1:53 remaining.
