It's not the weirdest thing, especially if we pick up a good chunk of his salary. They are clearly in a throw in the towel mode, they have enough holes that he could get ABs, and they could flip him. I'd actually like to free up some roster spots, too. i'm not sure I'm in the cut them mode like you are, but the short bench with Nunez is a bit of a problem.
Nunez is a waste of roster space. Gallo was, for a while, a major leaguer, although that was several seasons back. As someone suggested, he would be Designated Fielder. Otherwise, he offers nothing except strikeouts.
I gave up on Robles in 2021, but Victor is more useful than Gallo.
