Every 13 seed to upset a 4 seed in March Madness history

Upsets are the heart of the March Madness excitement and with the familiarity of seeding, we generally now what to expect and how impressed to be by it. We, intuitively understand the different talent gaps between a No. 2 and a No. 15- seed and a No. 7 and a No. 10-seed and why an upset in the first almost never happens and at least one upset in the other is almost guaranteed.

A No. 13 upsetting a No. 4 seed isn't the most rare feat — it's happened 32 times going back to 1985, roughly once per year. There have only been 10 years in that span where we didn't see at least one No. 13 beating a No. 4. The last was the 2023 tournament when Furman upset Virginia, 68-67.

Oklahoma has been particularly vulnerable in these matchups, losing as a No. 4 three times — in 1992, 1995 and 2001. They also pulled off a win of their own as a No. 13 seed over Arizona in 1999. To date, Ohio is the only school that has pulled off two first-round wins as a No. 13 seed. However, that could change this year — No. 13 Vermont will play No. 4 Duke this year and UVM also managed an iconic win over No. 4 Syracuse in the 2005 tournament.

Who knows if we'll see one in the 2024 tournament but the rest of the matchups — No. 4 Auburn vs. No. 13 Yale in the East, No. 4 Alabama vs. No. 13 Charleston in the West, and No. 4 Kansas and No. 13 Samford in the Midwest — have plenty of potential.
