Upsets happen, and rather frequently. One of the best parts of the open tournament portion of the season is that we see A LOT of upsets.

By our count, there were 32 wins by wrestlers either not ranked at all or ranked below the opponent they beat. While all are worthy of recognition and notoriety of some kind, these are the twelve that blew our minds the most.

149: Trey Grine, Tiffin over #11 Josh Maruca, Arizona State

This 10-7 quarterfinals win at the Michigan State Open is what we call a "google loss," and here's what we found on Grine: he went 0-2 at Division II NCAAs last year, is a criminal justice major, and from Fremont, Ohio. Match below.

174: #2 Zahid Valencia, Arizona State over #1 Mark Hall, Penn State

Probably not an "upset," but important to note. These two were teammates at junior worlds, and of course we all know what happened last time they met.

174: Ben Harvey, Army over #7 Ethan Ramos, UNC

Last year, Harvey had a 7-6 loss to Zahid Valencia. That's not an upset of course, but it speaks to the quality of wrestler Harvey is. He avenged a 5-3 loss to Ramos with his last second takedown in the Hokie Open semis.

141#15 Chad Red, Nebraska over #6 Tommy Thorn, Minnesota

Weird things tend to happen in upsets, and in this one the new danger zone rules from neutral came into play. Make your ruling on the OT takedown below.

125: #5 Nick Piccininni, Oklahoma State over #2 Darian Cruz, Lehigh

This one was "supposed" to happen at the Southern Scuffle last year. It didn't, and any time someone beats an NCAA champ it's an upset.

133: Dennis Gustafson, Virginia Tech over #13 Cam Kelly, Ohio

After giving up the first takedown, Gustafson scored eight unanswered and held on late to win 9-7 over Kelly in the finals of the Hokie Open.

141: Yahya Thomas, Northwesterm over #17 Cole Martin, Wisconsin

An overtime win on the backside at the Michigna State Open, Thomas is yet another example that the number of true freshmen who come in ready to compete right away is on the rise.

125: Jake Gromacki, Clarion over #7 Zeke Moisey, West Virginia

Similar to Cruz, only slightly more unexpected. Gromacki went 1-2 at NCAAs last season, and just beat a finalist. Watch how he did it below.

184: Nick Reenan, NC State over #7 Zack Zavatsky, Virginia Tech

Just because you're redshirting doesn't mean you can't still earn yourself some big wins.

Larry Early, ODU over #12 Paul Fox, Stanford

A couple years ago, this likely wouldn't have been considered an upset, but the 10-4 win in the semis of the Hokie Open is now that Fox was an All American last year.

197: Nathan Traxler, Stanford over #8 Daniel Chaid, UNC

When he was in high school, many thought Traxler had the potential to one day be a Division 1 All American. His takedown in overtime of the Hokie Open semis is yet another example of it.

Brett Dempsey, American over #12 Jere Heino, Campbell

American put it on Campbell, and this 6-5 win in the second match of the dual helped kick off the rout.
