Yes, 100% on Dalbec and Cordero.
Marwin hitting under .570 is unacceptable, and being 9th in team PAs seems absurd, but Arroyo has been out, and Kike was needed in CF, so I can understand most of his playing choices.
Personally, I'd have limited Marwin's playing time more, but I don't see Arauz as being a better choice, so I'm okay with what Cora did.
I was for demoting Cordero about the same time he was- somewhat before, but not by much.
I was for finding a platoon partner for Dalbec earlier than Cora/Bloom, but not by so much more time for me to complain about the timing.
I don't believe 100-200 PAs is enough to determine who a player is. With Marwin, we knew we had about a .700 hitter who in this new era would adjust to .650, so .550 is not "way off."
Cordero & Dalbec ahs very limited ML sample sizes, so they both needed longer looks, IMO.
Again, I'd have gone shorter on all 3, but not by enough to say Cora/Bloom messed up.
I'm glad they did not give up on Renfroe.
