Yeah, we’ve gotta keep SWR. His velo was up, his Stuff+ was 94 (up from 87 with the Twins), and his Location+ was 108 (up from 95).
Seabold is the obvious cut and Macko (who is a little overrated right now) is optionable.
Beyond that, I wonder if Corbin’s days are numbered. Doesn't seem fair but he’s looking like a fringe #5 again, and I’m not sure he fits in the bullpen.
Even if Scherzer struggles and is IL'd, SWR and Bieber are probably better options than Corbin anyway and Yimi may be coming back as well. And if Corbin is throwing like junk, is he really worth cramming in the bullpen instead of just cutting him loose? If we get desperate to the point we need to go back to Corbin we could just use Chad Dallas and make a move at the deadline.
There’s always the Phantom IL too (aka the Dodgers Special). Maybe Corbin would be open to that but I think Fisher and Miles could be good Phantom IL candidates as well. Fisher is on pace for 85 innings, and Miles is already at 41 after barely pitching in pro ball, though I bet the Giants are watching that situation like a hawk.
