To be fair Ramos was sent down because of basically losing his head. He has good stuff, has a scary slider/slurve that if it develops further could be a plus plus pitch, even at the ML level. He certainly has end of game (setup or closer) potential, he just needs to continue to demonstrate that last years brain fart wasnt normal (or at least he can control it enough not to appear completely nuts, because all closers are pretty crazy anyway). I actually see him in an 8th and 9th inning role for 10+ years if he can keep his head and control his best pitch and mix in his solid fastball.
I wouldnt trade Ramos at this point without a huge return. I think he is undervalued because of last years bump, which hopefully was just a young, overly excited guy losing his head a little.
Neris to me is also a sell low candidate at the moment. He may not be a closer, but he is a very good reliever with a very good fastball and a cutter that is unhittable. He needs to get better at mixing them in, and honestly some of that is just his catchers getting a better feel for him (remember, Alfaro has only caught him for less than 20 innings still). His potential so outweighs his current value that he is almost untouchable IMHO because you arent going to get much for him at the moment and that would be criminal. I would be surprised if he isnt still pitching in 2028, he has all tools and makeup, he is just being put in a position he isnt quite ready for yet.
