LAS VEGAS, July 17 - Anthony Roberson's 24-points led the Chicago Bulls to an 80-74 victory over the Oklahoma City Thunder in 2009 NBA Summer League presented by EA SPORTS action at the Thomas and Mack Center on the campus of the University of Nevada - Las Vegas Friday evening.

"The big thing for today's game was to get the win." said Roberson. "We came here and dropped the first two, so today felt like it was a must win. It all started on the defensive end, we were able to get steals, we stuck it out and stayed together at the end to get the win."

Roberson scored a quick four points midway through the fourth quarter to stretch the Bulls lead from three points, 70-67, to eight, 75-67 and Chicago never looked back before securing the six-point victory.

Roberson had the hot hand from horn to horn, scoring the first seven points of the game for Chicago and helping to give the Bulls a one-point edge, 18-17, at the end of one. James Augustine contributed with six boards in the first.

D.J. White kept Oklahoma City alive in the second quarter, netting six of his ten points in the period. Roberson scored five more in the second to bring his halftime total to 12 as Chicago ended the first half on a 12-4 run bringing their lead to nine points, 40-31.
