I would think the poor arm won't factor in that regularly at 2B where it would prevent him from being an everyday option there, particularly if the bat plays.
Other than throws home or to third, where would a poor arm as a 2B come into play? The answer may be during large shifts, but could you leave him in the regular 2B spot and slide the SS or 3B into shallow RF for the exaggerated shifts? The main issue then would be shifts on right-handed hitters...
I think the bright lights thing has some merit and wonder if he's--perhaps--the top prospect on the team most hindered by the loss of the 2020 minor league season. I'm still stubbornly optimistic he can develop into a solid regular (which was really all I expected from the get-go).
I think if he can develop into a solid everyday RF (with some versatility to move around) that could slide in around the 7-hole in the order, that would be a solid option. I'm still hopeful that between Diaz, Hays, Mullins, Santander...and eventually Kjerstad, it's enough to push Mountcastle to 1B/DH. Add in Rutschman and the team is pretty set offensively save for 2B, SS, 3B which I'm also hopeful at least one of Vavra, Hall, Bannon, etc. can develop into an average option....but that--of course--is a whole different topic.
I think Akin's floor is higher, but Lowther has a better chance to stick as a starter. I was a believer after his Bowie year and still think he will overcome his less than sparkling metrics because his deception helps his stuff play up.
I don't believe Harvey is eligible. I think he has too much time on the 25-man roster. MLB Pipeline removed him as well.
I will say if he was eligible, he would be coming up soon, but would not be above the guys listed so far.
