Milwaukee placed six players in double figures. The Bucks pulled ahead in the second quarter and led by double figures for most of the second half.
Bucks guard Beno Udrih left the game in the first quarter after he banged the back of his head on the knee of teammate Larry Sanders. Udrih was face down on the floor for a few moments while being looked at by Milwaukee's trainer. He walked to the locker room on his own, but didn't return after playing only 45 seconds.
"I'm not sure what I hit on Larry's leg," Udrih said. "I just got a bump on the back of my head."
Udrih was taken to a local hospital, where the results of a CT scan for a concussion were negative. He returned to the arena and flew back to Milwaukee with his teammates.
Guard Dion Waiters, taken by the Cavaliers with the No. 4 pick in the draft, scored two points in 14 minutes and was benched by coach Byron Scott early in the fourth quarter. Waiters drew Scott's ire for taking a 23-foot jump shot and was immediately pulled from the game.
"I drew up a play and he messed it up," Scott said. "To me that was a lack of focus and I figured he didn't need to play the rest of the game."
