I may be under-estimating Wilson and over-rating Ynoa. I really didn't see Wilson as an MLB pitcher after he wore down last year. Maybe he is healthy this year? Ynoa's MiLB stats are strangely similar to WIlson's. Sure, move Ynoa and Nuno to the bubble list as well.
So that makes Nuno, Aquino, Wilson, Ynoa, Mancini and Gentry for 3 spots. I can see the case for/against any of these guys.
IMO Ynoa doesn't make the Opening Day roster but is in competition with Aquino to be called up for the April 15th start. They will continue the competition in Norfolk the first week of April.
Wilson is picked for OD long man in the pen.
We would need some serious shenanigans or injuries. Now we have some options in case of injury or if Gentry or Rickard struggle at any point. It would really help the payroll and extensions if 2018 looked something like this
AAA: Stewart, Hays, Mullins
Good job. I'd take your 21. Add
22. Smith (if healthy)
24. Last BP arm
25. Tavarez (until we need a 5th SP on 4/15 or extra BP arm)
DL: Santander and Tillman
Both rule 5 guys make it but might not survive April with us.
