Well, I think I will start with some guesses about the positions:
SS - A-Rod.
He seems to have nailed this spot down.
2B - Grant Mac
I think he will be here when not pitching. When pitching I will give the nod to Schultz.
1B - Dalton Reed
Big bat and he will be hard to unseat here. Could DH.
3B - Breydon Daniel
He is versatile and might move around, but I think he goes here.
C - Kessler
I think this might be a bit by committee with Marshall spelling him some, but Kessler will get the lead.
Here is where it gets super hard:
CF - Rook Ellington
This kind of hurts to say because I think Hill would be best here, but I think the coaches really like Rook, and he'll be slated here.
LF - Cam Hill
He will fit in anywhere the OF, and should do fine over in left.
RF - Jaren Shelby
This is a wild guess. I would put Shinny here as he is tearing it up, but I feel that Shelby has to have a role.
DH - Ryan Shinn
I think Shinn and Shelby rotate some. Unfortunately, I fear that Collette may still not be healthy. I don't know this for sure, and don't really have any insider information, but that is just a fear of mine.
