Clark v. Hathaway will certainly be a big one tomorrow, they should wrestle right around 9:45A to 10:00A if I understand the schedule right.
The session starts at 9:00A and both 3A and 2A championship brackets are wrestling first, so...what I think is that they will have 4 mats going on 3A and 4 mats going on 2A. With 126 being the 4th weight class I would estimate they will be on the mat somewhere around 9:45A.
Another 2nd round doozy should be: 2A 120 with two undefeated, tough wrestlers squaring off. Dylan Peters (Den/Trip) v. Sawyer Farris (NL/MU). I think that match should go off around 9:30A or so.
