No. 1 seed Duke is heading to the Final Four after a 66-52 victory against second-seeded Gonzaga in the South Region final, while No. 7 seed Michigan State upset Louisville in a 76-70 overtime win in the East Region championship Sunday. The Spartans will head back to the Final Four for the first time since 2010, which was also the last appearance by Duke Coach Mike Krzyzewski. This will be the 12th appearance for Krzyzewski, who has four national titles with the Blue Devils. Duke will face Michigan State in the first national semifinal Saturday and Kentucky will go head-to-head with Wisconsin in the second national semifinal.
