I don't think I have seen any posts about upsets. I don't follow ever class carefully but who were some of the biggest upsets?

Just some matches of interest from B-2
135 Jukes ES over Hartnett Gre in the Quarters
Hartnett avenged in 3rd and 4th place match
145 Schany BLA over Randall Skutt
145 Grossman GRE over Boehmer Ben
145 Grossman over Mixan Gross
145 Randall over Boehmer Ben (After Schany match Randall looked pretty beat up)
152 Bannister BLA over Hovey Benn in the Quarters (dropped down and had to face Richardson to go to state)
171 Harrill BT over Wang Benn

Just a few matches that I saw

In the C4 District
Shelbourn Valentine over Frederick Hershey was big. Miller of Sargent-Burwell beating Trout of Mitchell in the finals. Coyle of West Holt over Gross Ainsworth in the 171 finals. Their were some other minor upsets, but I felt like those were the big ones.

A notable near upset was C2 152 heartbreak round. 2 seed OC kid is up 3-2 and gives up a take down with about 3 seconds left and the C/V kid thinks it's over and gets up, giving an escape that ties it. OC wins in OT. 2 seed 6th ranked senior qualifies by the skin on his teeth.
