In the first day of full-schedule first-round play, No. 12 seed Yale beat No. 5 seed Baylor, securing the first tournament win in Yale’s history. And in double overtime, another No. 12 seed, the Arkansas-Little Rock Trojans, knocked off another No. 5 seed, Purdue. And that was just day one. Sixteen more games are played today, spread across four networks: CBS beginning at noon ET, TruTV beginning at 12:30 p.m. ET, TNT beginning at 1:30, and TBS beginning at 2.
