I'd re-sign Nola, keep Lorenzen if possible and let Hoskins walk.
I keep Harper at 1B, Casty in RF and Schwarbs as the main DH.
I'd then focus on trading for or signing a good bat in LF and slide Marsh back into CF.
Rojas needs more seasoning in AAA and could certainly have a bench role later if he improves.
The bench is the other focus - we need a much better PH option and I never thought Sosa was worth keeping so I'd replace him as well.
I'm not sure how they feel about Walker, but it was really weird that they never pitched him and from reports he is not happy. I think we need him or someone as a #3/4 with Suarez; if not what are they going to do with him? Trade him? Strange situation indeed.
Pen is pretty set, but they do not seem to trust Soto either and I'd let Kimbrel go. With Hoffman, Alvarado, SD, Kerkering & Strahm, we have the foundation and need 1-2 other options.
If Nola is back, the rotation also seems pretty set with Walker, Suarez, Sanchez and Lorenzen battling for spots with the pen as the alternate spot.
I'd like to see Rob change the lineup so it is not so top heavy and hopefully the new LF can help lengthen it more. We have a good mix of LH (Harper, Stott, Schwarbs, Marsh) and RH (Turner, JT, Casty and Bohm) hitters. If we get upgrade LF, we could be even better offensively.
