Trying to give the much shorter, schematic version: Cherington has to be careful about the deals that he makes. He needs to get real upside guys, and the solution he has in mind may very well be a sort of extended and long rebuild where he trades for PTBNL returns right now because it's the loophole to get guys who are not in the alternative sites right now. The obvious extra caveat there is that some teams aren't even sharing data of their alternative sites, where players are just doing glorified practice anyways, and the low minors guys are spread all around the country and parts of the world seemingly doing various ad hoc training regimes.
So trading for PTBNL low minors types is more fraught than it is when there's a guy in single-A not quite on the radars yet that you want to try and scoop up, etc.
My hopes for the deadline remain in part to try and shuffle out a substantial chunk of players and open up some opportunities for talent that hasn't clicked elsewhere yet. With Oakland dealing Barreto, the biggest names left in my mind are Clint Frazier, Andujar, and Touki Toussaint.
Frazier has probably played his way onto a bunch of team's wish lists, including perhaps a team that is not really rebuilding and so could use him as part of their immediate plans and long term. The obvious ironic team that pops in my head is Cleveland, who of course dealt him in the first place. Maybe he's part of a Clevinger package, but they'll want more. I think Frazier is probably not in the cards for us, but I'd jump at the chance to get his power into our lineup.
Andujar is a quite interesting guy to keep an eye on IMO. He's really struggled, and now again has been demoted. He does not have a position or seemingly a future with the Yankees. It makes some sense that they will just keep him like Frazier as super depth, figuring maybe that he'll work some things out or eventually find a spot as a fill-in player for three weeks of solid performance. On a brutal level, the Yankees can afford to simply do that – it's quite literally what they've continued to do with Frazier, where they've been more successful.
But Andujar's value has to be tanking, and maybe the time is right to strike and gamble for him. The question is where you'd play him in Pittsburgh. He could DH, but his defense is atrocious. If we got him, I could see it as a sneaky longer-term DH potential plan, with some inkling that perhaps we try him at 1B and consider moving Bell in the offseason (something I am not totally opposed to, but I would approach Bell and see if you can buy out one of his arb years this winter, something that necessitates another long ass post for me to try and defend).
That brings me to Touki, who I think is the player I covet the most. Atlanta needs dependable starting pitching and can't afford to let him pitch right now. He's looked very good in relief roles and has at least put together good starts at the MLB level. He's 24 and lines up pretty well with Keller as someone to build around. As far as what's available, he's maybe the perfect option of long-term impact, talent upside, and slightly on the outs with his own team in need of a scenery change. Atlanta surely doesn't want to let him go cheap, but I'd leverage him into any deal for Musgrove, Williams, or anyone else they'd want (it would have been a dream come true if Moran was healthy enough and they wanted him and we did a swap).
