The women are playing now: Tennessee and Notre Dame and surprisingly, TN is losing! There is still 3 minutes left of the game and anything can happen, but it will be a surprise if TN loses.
Edit: Notre Dame just beat TN for the first time in the 21 games they've played against each other. This ND team has never played in the Final Four (last time they got this far was 2001). They are very excited!
