The situation with Perez is mystifying. There's no structural damage..apparently no inflammation within the tendons and ligaments...just pain from "muscle weakness". I've been following baseball awhile...back to the days before they understood what a rotator cuff is...and I don't recall a multi year diagnosis like that.
Does he have a problem with his motion they can fix? Does he have to learn to pitch through a little discomfort as he builds arm strength? I'm not him...so I don't know what he's feeling. Ultimately you have to take him at his word that it hurts too much to pitch, but the entire scenario really seems weird.
When discussing the OF everyone mentions Reyes, Jones, Demeritte and Stewart but they forget...they forget that Bonifacio is lurking in the weeds like a snake...ready to strike to claim his roster spot
