Let's keep on breaking it down.
40 man roster guys...
Hunter Gaddis
Konnor Pilkington
Xzavion Curry
Joey Cantillo - performance/results accelerate this fella.
Cody Morris - how injured is he? Likely enough to be out longer than TMac?
Next up - these guys require roster spots.
Battenfield - Will have to perform. Seem pretty out to me unless the plan is to give him the Kirk McCarty roster treatment.
Logan Allen - rostering him (like the following) requires a long term roster commitment.. Will have to perform, as others in this same boat probably have priority... See:
Tanner Bibee - If he hits 5+ dominant starts in the early going and the need is there... Don't look back.
Gavin Williams - If he hits 5+ dominannnnn... Wait see above.
