The first half of the Final Four is set and two No. 1 seeds are through.
Florida and Duke won their regions on Saturday, with fellow top seeds Houston and Auburn set to play on Sunday.
Florida became the first Southeastern Conference team and No. 1 seed to earn a trip to San Antonio behind a clutch performance by Walter Clayton Jr.
His team trailed by nine with three minutes left when Clayton took over, hitting a pair of late 3-pointers to push Florida to an 84-79 win over Texas Tech in the West Region final on Saturday.
