It's ACC semi-final night in college basketball. Or, you might want to call it top-20 night in the south. Duke, Virginia, Notre Dame and North Carolina make up the ACC field.

In the first semi, #3 Virginia meets #19 North Carolina at 7pm.

The second semi features #2 Duke and #11 Notre Dame at 9pm.

A Saturday night ACC championship game awaits the two winners but it's more than that. Duke is trying to maintain a number one regional seed for the upcoming NCAA tourney. Virginia appears headed for a number two regional seed but if the Cavaliers were to knock off Duke in a title game do they get a number one spot?
