Off the top of my head, Rex Brothers and Nick Greenwood have been released already, and Edgar Olmos was traded, so they wouldn't be included.
I would recommend these changes.
SP Aaron Brooks will definitely be on the AAA roster.
RPs Aaron Crow and Manny Parra will probably be AAA relievers.
RP CJ Riefenhauser is on the SCEA roster, so he will probably be included in the OSFM set.
RF Shane Victorino signed a minor league contract and will probably start with AAA.
This is closer to what I would recommend:

It is apparent that we have a ton of A level pitching prospects, making it difficult to determine who fills out AA and below. We also have a ton of OF depth from AAA down. I wouldn't be surprised if a few of them get cut like Matt Murton, Ryan Kalish, and Mike O'Neill simply because we do not have enough room to play them at the level they should be playing. This is why it is a good thing that OSFM doesn't release until after opening day, so all the waivers can be cleared and the rosters become more apparent around the league. Anyway, my thoughts, love to hear some feedback.
