On the other hand, I wouldn't worry about making roster decisions based on parallels with what the Angels think. I think the bigger priority here is to patch something together to bide time until Vierling/Meadows return while at the same time keeping Greene out of CF as much as possible.
Now, Moniak's 2023 was fueled by a .397 BABIP, so I agree that his 2023 OPS should be discounted as such. But he is a 110 +OPS vs RHPs on his .318 BABIP vs RHPs over his career. So, if he can field CF well enough and maybe just maybe hit enough at the bottom of the order to fill a platoon role in CF, I think its worth consideration. He'd be cheap, he'd be expendable, he'd fill a short term role.
