Two number one seeds were upset and another had to hang on in the rideout.  The big upset of the morning was recorded by Leo Urbinelli of Cornell winning in the rideout over Ryan Bernholz of Lehigh.  At the next weight Cornell was the recipient of their number one seed falling as Ryan Bonfiglio of Princeton won a last second match over Clint Watenberg.   Matt Goldstein from Lehigh escaped in the rideout to prevent Cornell's Tom Waldron from pulling of a major upset.     Lehigh and Penn will each send four tonight's finals followed by Harvard and Cornell's three.  Another big story evolving is the return of Princeton's wrestling program returning to prominence in the EIWA's.
