I was looking at the minors some today.
AAA: Williams, Johnson and Zantazny
Johnson has the best potential with a mid 90 fastball with movement and a true hammer. Other 2 are fringe. Problem is Theo has been stocking up on career AAA SP for depth. Johnson would have to win a spot in their rotation. His injury track record is his drawback.
AA: Tseng pitched 22 games here but put up a 4 ish ERA. With them adding depth at AAA you have to think they will hold him back here. He really didn't do much to prove he was deserving of a promote. Added to him will be Underwood who was injured and bounced around some. He needs to get back on track here. Clifton is due to hit here also. With most SP prospects hitting a wall at this level you have to cross your fingers one breaks through.
MB should have De La Cruz, Paulino Sands and Steel. Keep a eye on Paulino. Has the make up that could excel in the bigs.
SB Cease and Hudson. Not sure on Hatch as he didn't pitch.
So over all it is not bad but we have seen Theo and Jed use Iowa for injury replacement for starters. Tenn is where the talent starts.
The wild card is Johnson. They really don't need him to start as they have filled that need. It is up to him to bump guys out of his way.
So as far as a inhouse answer. Unsure. The system has shifted to pitching talent taking over the top 30 list but the guys that look like they may impact as a distance away.
So if I was Jed I would go after Ross pretty hard and let the system work it self out. I would guess if Williams rebounds from injury that he would get the first shot. He seems like a solid back of the rotation guy that can give quality innings. But nothing exciting. After that Underwood has #2 potential. He comes back strong we will be talking about him soon.
