I'd say, right now, with Schwarber's defense at 1B in question, Shaw might be more valuable than Cordero & Arauz. I like Munoz, but I'll leave that choice to Bloom.
When we expand to 28, my guess is we go with 14 pitchers and 14 everyday players. With 100% health, I see no room for Shaw either, but he may be close to equal to our 14th everyday player.
14 pitchers:
Sale
Eovaldi
ERod
Pivetta
Houck
Barnes
Ottavino
Whitlock
Richards
Perez
DHern (may miss Sep)
Taylor
Sawamura
Last pitching slot:
Brasier, Valdez, Davis, Robles, Rios, Seabold, Andriese
14 Non Pitchers
Vaz
Plawecki
Schwarber
Dalbec
Arroyo
Devers
Bogey
Verdugo
Kike
Renfroe
Duran
JD M
last 2 slots:
Arauz, Cordero, Wong, Shaw, Santana (DFA'd by SEP?) & maybe Munoz (not on 40, right now.)
To make room for Munoz on the 40, we may first have to "make room" for Brasier (60 day IL) &Taylor (COVID list).
