Ramos is still a solid young reliever. He's had ups and downs (literally). He was quite good last year. He didn't even pitch that badly last night but there was no margin for error and he made one. Kimbrel (or any of our unavailable guys) might have made one too.
They do need Hunter back. And at some point they probably will need to get rid of Alvarez or Nicasio (or both) just so they can have more optionable arms in the mix. If there wasn't an off-day tomorrow they might have considered sending down Ramos (not because he was awful, but he pitched last night and is the only pitcher who can be sent down).
On the other topic above, I wouldn't compare Hoskins or Nola to Acuna or Soto. They were both college players who took their time arriving in the big leagues. Hoskins could have won ROY if he'd come up sooner but he was already 24, not 19. And Nola didn't have anyone viewing him as elite in his first two seasons, just solid. Even Howard was quite hold of course but he and Rollins are the last big-deal instant impact rookies we had (at this time last year I think we'd already realized Kingery wasn't going to win it).
