NORMAN, Okla. -- — Chuck Harris buried a 3 to take the lead and Simas Lukosius grabbed a clutch defensive rebound and hit a pair of free throws with 12 seconds left to give Butler a 66-62 overtime win over Oklahoma in a Big East/Big 12 Battle Tuesday night.

Hughes got a tip-in and Harris stepped behind a screen and drilled an open 3 with :35 left to give the Bulldogs the lead. Harkless drove for a layup that rolled off the rim and Lukosius grabbed the rebound. The freshman from Lithuania hit both free throws for a three-point lead and Aaron Thompson rebounded Umoja Gibson's missed 3 and hit one of two from the line to set the final margin.

C.J. Noland scored with 13:14 left in regulation to put Oklahoma up, 41-28, but Butler battled back, using a 9-0 run capped by a Harris trey to cut the deficit to 44-41 midway through the half. After Jacob Groves hit a jumper and a 3, Butler went on an 11-0 run that included a Lukosius 3 for the lead and a Harris jumper for a 52-49 lead with :22 left. Goldwire got Oklahoma within one and Lukosius answered with two free throws before Harkless buried a 3 with :02 left to force overtime.
