ATLANTA --- Joe Johnson scored 30 points, Marvin Williams added 22 and the Atlanta Hawks pulled away in the closing minutes for a sloppy 88-83 victory over the Charlotte Bobcats on Friday night.

Charlotte went ahead for the final time in a back-and-forth final period when Raymond Felton hit a jumper from the top of the key, giving the Bobcats an 81-80 lead.

But Williams put the Hawks ahead for good on a 3-pointer with 2:12 remaining. The Charlotte defense collapsed on Johnson, who swung the ball to Maurice Evans. He whipped it around to Williams all alone in the corner.

Rookie D.J. Augustin led the Bobcats with a career-best 26 points, only to miss a fallaway jumper from the baseline when Charlotte needed it most. Evans then came up with a big hoop for Atlanta, swishing an 18-foot jumper with 1:24 left.

The Hawks fell behind by 13 in the opening period and had to overcome 21 turnovers.

Mike Bibby, who had only four points through the first three quarters, came alive in the fourth from beyond the 3-point stripe, hitting three of the long-range shots. He finished with 14 points.

Evans added 10.

Augustin, who was averaging a modest 10 points a game, doubled up on that before the third period was done.

But Gerald Wallace, with 17 points, was the only other Charlotte player in double figures. The Bobcats hit only 42 percent (33 of 78) from the field.

The Hawks got off to a miserable start. They went nearly five minutes without scoring, missing four consecutive shots and turning it over three times as Charlotte bolted to a 16-6 lead. The Hawks kept barking about calls until Johnson was hit with a technical.
