Again, the way the mats are being assigned on 8 mats (10 weights on 8 mats), I believe Facundo will be the first PSU wrestler up - 7th match on Mat 6.
Actually looks like they are wrestling 125 & 133 on all mats followed by each remaining weight (141-HWT) being wrestled on a per mat basis. This is different than what Track was showing early this morning when you looked on their Mat Assignments by Weight.
Given the current way mats are assigned, RBY should be first up but not sure what mat assignment.
