I count six guys I think get added.
Perez, Bergner, Gipson-Long, Meadows, Lipcius, Olson
I wouldn't rule out a trade with a team that has a roster crunch. That is a good arbitrage opportunity.
As for the chopping block?
Miguel Diaz, Michael Papierski, Kyle Funkhouser, Jose Cisnero, Harold Castro, Sean Guenther, Brendon Davis, Kody Clemens, Zach Short, Andy Ibanez are all possibilities. And if you want to non-tender Jeimer, you can DFA him today and non-tender Friday.
