The NCAA men's basketball tournament — March Madness, that is — thrives on the magic of the first-round upset, those moments when Cinderella achieves that "One Shining Moment" and busts your bracket.
The 2021 men's basketball tournament provided one of those upsets on the first day of action. No. 15 Oral Roberts knocked off No. 2 Ohio State 75-72 in overtime Friday, and that lands in the top 10 on our list.
Since the NCAA tournament expanded to 64 teams in 1984-85, there have been 60 first-round upsets where a teams seeded No. 13 or lower beat teams seeded 2-4 in the first round of the tournament. That includes 29 victories by No. 13 seeds over No. 4, 21 victories by No. 14 seeds over No. 3 and nine victories by No. 15 seeds over No. 2. UMBC made history as the first No. 16 seed to beat a No. 1 seed in 2018.
