It was a quieter week on the upset front, after the chaos had settled from the National Duals Invitational presented by Paycom.

Week 3 Rankings | Week 3 Upsets | Week 2 Upsets | Week 1 Upsets

The usual caveats apply. What look like upsets based strictly on the rankings this week may not look like upsets by the end of the year, or even next month. Additionally, some wrestlers that are unranked are only out of the rankings because a teammate is occupying a spot in the polls, meaning it could be less of an upset than it looks, or not an upset at all.

Upsets with a Difference in Rankings of over 20 or More

165: Sean Seefeldt, Penn over #11 Ryan Burton, Virginia Tech 2-1 TB

149: Max Petersen, North Dakota State over #12 Caleb Rathjen, Northern Iowa 6-5

133: #28 Evan Mougalian, Penn over #7 Dylan Shawver, Rutgers 11-4
