I agree on it being a big improvement. I'm just not convinced this 30 IP by Robertson in 2022 is the real Robertson, at age 37. What's the odds he comes close to those numbers going forward? (Surely, better than Barnes & Robles making a turn-around.)
I would not release Barnes, at this time, and not just about the money being a deterrent. I still have hope he can find himself. Once he comes of the IL, and not having any options left, makes keeping a 26 man roster slot for him highly problematic, but there are plenty of mop-up innings to go around, and at this moment, I'm not for cutting ties with him. I'd DFA Robles, yesterday. I'd put Diekman ahead of Barnes- maybe even Sawamura. (Danish can be demoted.) I'm on the fence with Davis.
We might even be able to trade Sawamura for peanuts and some salary relief. We might be able to trade Diekman, if we pay half or 3/4 of his remaining contract- again for just peanuts & $ relief.
