Looking at future BP options and there seems to be plenty.
Right now, guys with a year or two of service time at the ML level that IMO have a chance to still be around in a couple of years are:
RH- Withrow, Jenkins, Cabrera with Simmons on the DL. I think both Withrow and Simmons could potentially close.
LH- Krol, Alvarez, Cervenka.
At AAA and AA you've got:
RH-Ramirez (C), Kelly, Janas, Hursh, Younginer, Roney, Morris (C), Dirks (C)
LH- Rodriguez (DL), Marksberry, Kent, Minter (C)
And a couple of SP who look to me likely to end up in the pen and potentially close in LHP Banuelos and RHP Sims.
Obviously, all the guys with C by their name won't close and may never even have a chance. I think Minter is being groomed for that spot and Cabrera could be the guy as long as he gets enough control so he doesn't kill someone. But, if you need to get 6 or 7 guys next year (to mix with a vet or two), I don't see a lot of trouble. I do think they will likely lose some of these guys due to a crowded 40 man, so choosing who to keep and who to let go will need to be carefully considered.
This doesn't even take into consideration any wildcards like Cleto or anyone who hasn't appeared at AA ball or higher.
