Kevin Durant is showing no ill effects from his ankle injury.
Russell Westbrook has nine points for the Thunder, who are shooting a blistering 59-percent (13-for-22) from the field.
Atlanta was rolling in this one early behind seven points from Kirk Hinrich, but Joe Johnson took an elbow to the lip from Oklahoma City's Serge Ibaka and left the game. With Al Horford already on the bench in foul trouble and Josh Smith not available due to a sprained right knee, the Hawks were forced to throw in a bunch of reserves to take on the Thunder's first unit.
That did not go over very well. Oklahoma City erased an 11-4 deficit to take a five point lead into the break.
Hinrich lead all Atlanta scorers with nine points while Johnson had six in limited action for the home team.
Atlanta's all-star shooting guard spent a good part of the frame in the locker room, getting his bloody lip looked over by a team dentist. Johnson checked out fine and returned to the game with 2:54 left in the quarter.
