I forgot to include Stowers in speculating about Baltimore/Chapman. So that makes their young OF group include Cowser, Kjerstad, Stowers, Mayo, Norby, Beavers, Fabian, and Bradfield. That's 8 players, with the first 3 already being young MLB players, the next three knocking/pounding on the door, and Bradford still a bit away.
That doesn't include Austin Hays, who is in a small side platoon but seems to be mainly holding the fort. Mullins is still the CF on a lot of nights when I flip over to them, though his value has gone down this year and he is somewhat expensive, especially given that he's struggling more offensively. Still, I don't know that there's a slam dunk CF in the prospect group outside of Fabian and Bradfield. Cowser has played there a good bit, so he seems like Plan A for the moment from the outside looking in.
Since Mullins is one of a few veterans, I don't know that they'd trade him in the middle of a big postseason surge, but I also can't imagine that he's in their plans beyond this season.
I bring this up because maybe there's some room for a kind of needs-based trade, where we swap Chapman for Mullins and a corner OF prospect. Mullins is no sure thing, but he's much more passable than Suwinski and Taylor. If it took adding a pitching prospect, it would seem to be a good way to use depth to address present and future needs. This is a little too video game-y, but maybe they'd even be interested in something like Chapman/Taylor/Pitching prospect for Mullins/1 of Beaver/Stowers/Fabian. Taylor would be easier to hide in their lineup and gives them a true plus CF defender as a playoff substitution.
Ultimately, this is a lot of wishcasting, but I think Baltimore and Pittsburgh make good trade partners, for Chapman and potentially in broader deals too. Even in terms of just prospect for prospect, I would imagine they'd have interest in a close to MLB polished SP like Ashcraft or Harrington. A lot hinges on what other kinds of trades they make, but they have plenty of depth and a desperate need for pitching both now and next year. It's not even that crazy that they'd keep most of these guys in a potential Crochet trade, as they could headline that with just Norby/Mayo and their top tier catching prospect Basallo. Assuming you want 5 of those guys for starting spots and bench/depth (which itself assumes Mullins and Hays are gone in 2025), there's still multiple guys leftover with no place to play them.
The other thing I keep coming back to is that the major hole on this team is CF, and a big part of that is the Suwinski question. It really seems to me that management wants him to seize that job, but he's just fallen off so badly and not really shown any signs of his old self beyond a couple games at a time. In a way, I think you have to understand their patience, as the guy flirted with 30 HRs and had at least passable CF defense. Even not considering our depth, that's valuable and not worth just kicking to the curb. I think it probably would have been better for him to stay down in the minors, but we lack any semblance of depth.
In any case, my rambling here still leads me back to Jazz Chisholm. I don't think we'll get involved, so it's probably not worth dwelling, but I can't help but feel that he's the best of the available options given our situation. I would not complain about Rooker, but adding him complicates roster flexibility and roles, and still leaves us with a massive problem in CF that would be compounded more when he or Cutch is in RF (presumably).
Taylor Ward is slightly different in that he's better defensively, but he's more solid offensively and I'd almost rather live with defensive headaches for a way better bat, assuming cost is similar. Ward also just doesn't really address the CF situation.
Those are my thoughts on the state of things headed towards another long day with no baseball tomorrow. My gut says Baltimore probably just isn't trading Mullins right now, preferring to try and make a winning push this year and then a hopeful shift in the offseason (it seems easy to guess that regardless of how things play out for them, they won't want expensive veterans like Mullins and Hays for next year). But if you could pick him up, then that's an outside the box way to get a better CF who is more passable defensively.
Jazz is a better target in my view, because he's got way more offensive ceiling. It's very possible that we haven't seen his best MLB season yet, and so if things go well, you could hit huge with him in 2025 and 2026. Even as things stand, he's a well-above average bat who adds speed at the top of the lineup along with power. He can play well enough to address our major weakness for this year and the years to come, and maybe Suwinski still figures it out in a corner, or we can re-evaluate things in the offseason by acquiring a dedicated RH bat who can mash lefties. Lane Thomas would be perfect in that mould (and I think all else being equal, I'd rather try for him than Ward), but that's a topic for a different day and I'm not trying to add any more to this.
tldr; is that Jazz checks the most boxes. He's the riskier swing, but I assume the bidding won't be as intense. You can pay an adequate price and then maybe swing some minor deals as well -- I'd be reticent to sell low on Suwisnki, but maybe there's a swap out there that makes sense. Rowdy has performed enough that I think you just ignore 1B for the time being and put all the eggs in finding an outfielder, above all a CF.
