Joe Johnson finished with 22 points, and all five Atlanta starters scored in double figures, as the Hawks topped Philadelphia, 92-85, in the second game of a home-and-home series.
Josh Smith had 18 points and 10 rebounds, while Al Horford grabbed 12 boards to go with 10 points for the Hawks, who lost at home on Friday, but rebounded to win their sixth out of seven contests.
Marvin Williams scored 18, and Mike Bibby 10 for Atlanta, which holds the eighth playoff spot in the Eastern Conference.
Andre Iguodala led Philadelphia with 25 points and grabbed nine rebounds, but the 76ers missed out on a chance to pick up ground in the playoff hunt. Philadelphia clinched a postseason berth with its win over the Hawks on Friday, and could have moved within two games of Cleveland for the fourth seed -- the Cavaliers lost earlier in the day to Orlando.
