Despite the run, the Wildcats led by just six points with 1:07 to play and again, did there best to let the Bears back in. Ryan Anderson was alone under the basket for an easy lay-in, but Jawann McClellan inexplicably fould the freshman. The ensuing free throw cut the Wildcat lead in half.
McClellan made one of two foul shots and Ayinde Ubaka came right back and drained a three to cut the Wildcat lead to 66-65.
The Cats did not fold, Marcus Williams and Mustafa Shakur each made a pair of foul shots to seal the game.
