Memphis' Rudy Gay scored 21 points to lead five Grizzlies players in double figures in the 105-102 win over a listless Atlanta on Thursday that prevented the Hawks going clear top of the NBA's Southeast Division.
The Grizzlies pulled away late in the first half, closing on an 18-7 run that gave the visitors a 10-point lead at the break. They extended that advantage in the third quarter as Atlanta missed its first seven shots and turned the ball over three times.
The Hawks were coming off a 4-1 road trip that left them tied with Miami for the Southeast Division lead. But they looked exhausted in their return home, putting up ugly jumpers, playing pedestrian defense and struggling just to hang on to the ball.
Tony Allen and O.J. Mayo scored 18 apiece for Memphis.
Josh Smith led the Hawks with just 11 points, playing only 19 minutes.
