I agree with Jeff. I think we'll mostly have a 5 man rotation, with a 6th spot occasionally. I think we'll see a lot of shuffling between AAA and MLB this year.
Here's my guess at the depth chart, with remaining options in parenthesis.
C
Maldonado (0)
Perez (0)
Graterol (2)
1B
Valbuena (0)
Pujols (0)
Cron (0)
2B
Kinsler (0)
Cozart (0)
Cowart (1)
3B
Cozart (0)
Valbuena (0)
Cowart (1)
SS
Simmons (0)
Cozart (0)
LF
Upton (0)
4th OF
CF
Trout (2)
4th OF
RF
Calhoun (1)
4th OF
DH
Pujols (0)
Ohtani (3)
SP
Richards (0)
Ohtani (3)
Heaney (1)
Shoemaker (2)
Skaggs (1)
Bridwell (1)
Tropeano (2)
JC (0)
Scribner (3)
RP
Parker (0)
Bedrosian (0)
Alvarez (0)
Johnson (0)
Middleton (2)
Wood (0)
Paredes (2)
Noe (0)
Bard (0)
To start the year, I think we'll see the following:
MLB position player starters:
C - Maldonado
1B - Valbuena
2B - Kinsler
3B - Cozart
SS - Simmons
LF - Upton
CF - Trout
RF - Calhoun
DH - Pujols
That's 9. Now, MLB starting pitchers:
Richards
Ohtani
Heaney
Shoemaker
Bridwell
That's 14. Now, MLB relief pitchers:
Parker
Bedrosian
Alvarez
Middleton
Wood
Johnson
Bard
JC (long relief)
That's 22. Now, MLB bench:
C - Perez
1B/DH - Cron
OF - ??
That's 25. That leaves the following players in AAA:
Graterol
Cowart
Skaggs
Tropeano
Scribner
Paredes
All of our staters have options remaining except JC and Richards. JC is well suited in long relief, but I could see him making spot starts. Tropeano is still working his way back from surgery, so no real rush with him. Skaggs and Scribner can make spot starts or relieve as needed.
As far as future moves.. We still need a 4th OF. I'd like another bullpen piece. I could also see Cron flipped for a pitcher with options, with Cowart then used as a utility infielder.
My target for 4th OF would be someone like Jarrod Dyson. Might be tough to convince him to take a bench role though. Perhaps a Peter Bourjos reunion instead.
