I think Q will probably get promoted just ahead of the deadline for playoff eligibility on some sort of non guaranteed multi year contract.
This will give the Cs an open 2 way to get a long look at a developmental prospect.
If you project forward the Cs roster is pretty set for next year absent a trade of a rotation player or the Cs 1st round pick.
Right now Tankathon has the Cs with 3 picks in the draft and they have 2 or 3 potential roster slots next year, assuming they resign Tilman, something I expect to happen.
Luke, and Svi are not under contract next year and the a 1st round pick will likely take one of those roster spots and the two 2nd round picks will probably be offered 2 ways or be international stashes. I assume Svi will not be back.
Then it's just who gets kept on 2 ways and do the Cs keep an open roster spot next season to keep some flexibility to be opportunistic with FAs or unbalanced trades.
