I think we now know enough to reasonably speculate.
C Gomes/Suzuki
1B Thames/Zim - This platoon should produce nicely.
2B Howie/Cabby - I'm guessing Castro mainly plays 3B. Cabby keeps Howie fresh with 2-3 starts a week.
3B Castro/Cabby - Castro is much better against lefties, so Cabby can start against some tougher RH matchups.
SS Turner/Difo - I think Difo makes the team as a utility guy.
That's 9 IF. If Kieboom forces his way up, then Cabby essentially takes the Difo role. That would be ideal. If Kieboom isn't the answer, then a 3B bat at the deadline is an option, and likely could be the #1 item on the wishlist.
OF: Eaton, Robles, Soto. MAT is the #4 guy, unless he's traded to free some salary and replaced with Stevenson. In that scenario, who plays CF if Robles is out? Thames is capable of playing a corner spot if needed. That's 13 position guys. Do we maybe carry both MAT and Stevenson for 14 total position guys, and go with 7 in the bullpen? I'm guessing no.
Rotation: Max, Stras, Corbin, Sanchez, Ross
