If the plan is to add 2 pitchers to the 26, it's pretty crowded, even if 1-2 of the top 13 start on the IL.
I get the point about nothing to lose, but it would take a lot of injuries for a Rule 5 guy to stick. I agree on the no remaining options- Mata approach, assuming he's not traded. Watch him in ST'ing and make the choice.
We don't have many great pitchers on the 40, but we do have a boatload of decent and or promising pitchers that rate to be better than Mata and a Rule 5 addition:
Options remaining:
10 out of 13 are locks, if healthy...
None: Sale, Jansen, Martin, Pivetta
1:
2: Bello, Houck, Crawford, Wink
3: Whitlock, Schreiber
Borderline making 13 man MLB staff on opening day:
(Only 1 makes it, assuming we add 2 and no injuries)
0: Mata (I think he gets traded or DFA'd, unless 3-4 guys get hurt.)
1: Bernardino
2: Campbell, Murphy, Robertson, Walter
3: Kelly (Wikelman & Perales not MLB ready)
DFA? (Not considered for MLB opening day roster)
0: Llovera
2: Jacques, Weiss
