here is an article that has the Top 5. That list has Hamilton, Cingrani, Stephenson, Corcino and Travieso.
Even if guys who graduated were just removed and new players added in, Corcino would be ranked ahead of a guy like Jesse Winker, which he now isn't.
The list was updated at some point during or after June of 2013.
I found it. Mayo updated the Top 20's in the system on July 28th, 2013.
There is no excuse for Sean Buckley or Ryan Wright to be anywhere near the top 10 at that point in time.
