I personally feel they need better then just a MOR arm as a start, they need, if they can get, a guy who can slot between Imanaga and Boyd. They also can use another Starter if they wanna push Rea out of the rotation and I hope they do.
I'd like to see them have a rotation in August of Imanaga, TOR type, Boyd, inning eater, Horton.
They could use a backend reliever to help Palencia and keep him fresh, preferably LHed.
Lastly, a 3Bmen that can slot in the middle of lineup between PCA and Busch would be ideal.
Be nice if they can add a power bat for the bench and a super utility guy that can give outfielders and middle infielders a breather here and there but not counting on it, I think we'll probably just see a couple guys from Iowa come up to fill that need.
