But Virginia allowed only nine more points for the final 10 minutes and closed on a 22-9 surge to take a 31-22 lead at halftime.

The Cavaliers shot 46 percent for the half while allowing the Sooners to shoot at just a 31 percent clip. Five Virginia turnovers kept Oklahoma in the game as the Sooners converted five points off those turnovers.
