O.J. Mayo and Gary Neal put on a long-range shooting display, but it was Caron Butler's little 2-foot tip-in that made the difference for the Milwaukee Bucks. Butler rebounded a miss by Mayo with 24.8 seconds left for the go-ahead basket that halted a 13-point run by the Cleveland Cavaliers, propelling the short-handed Bucks to a 109-104 victory Wednesday night.
