I problem. I only noticed because I have run very similar scenarios to what you did and I neve had Madrigal In the line up. I think we all pretty much agree they need 2 bats and 1 needs to hit from the left side. At least one starting pitcher(preferably 2) and at least one pen arm. Bats are among guys like Naylor, Polanco, Bellinger, Lowe, Chapman, Hoskins, Belt, Alonso, Torres, JD Martinez to name a few.
Pitcher via trade is most likely Bieber. But Cease would be nice. And then there are several young arms as well. Via FA I would hope they are looking more towards Imanaga, Montgomery and Snell.
I realize some of these guys aren’t even abailable. Just doing best guess as to who could be had. There is also Bichette, Tucker, Vlad, Bergman crazy talk too.
