Neal, a senior who entered the game averaging 5.9 points, scored 10 in the first half. Smart played just 6 minutes in the first half and had six points on 2-for-4 shooting.

A 3 by Frank Booker increased the Sooners' lead to 16 points, then Nash committed his fourth foul with 14:17 remaining, and Clark fouled out with 12:18 to go.
A 3-pointer by Smart and a dunk by Brown cut OU's lead to 64-57.
