I'm fine with keeping Mancini (I know, SG, it's such a terrible idea) if he's strictly DH. He can't play in the field. Maybe 1st base every so often, but that's it. I'm getting the feeling that he's going to approach his 2019 levels now that he's had a full year post-cancer.
That said, if someone blows the Orioles away with a deal, you've gotta make it. But what does the market look like for a strict DH who just turned 30? I dunno.
Santander is the guy I'd look to move to make room for Stowers. I can't imagine there's a huge market for him either, but whatever.
