His OPS-against was .809, on a pretty routine .303 BABIP. Magill doesn't even need to regress.
Curtiss's AAA OPS was just above .600. Even accounting for the difference in opponent level (I tend to add .100 just as a rule of thumb), and a slightly favorable BABIP, that's a better season.
Oh yea, Magill's season as a whole was not good by any measure other than ERA (5.08 FIP, eek).
I just meant he regressed to the mean after his strong start with the Twins.
Magill in 12 appearances through 5/31: 1.53 ERA, .619 OPS
Magill in 28 appearances after 6/1: 4.85 ERA, .886 OPS
Based on his history and, ya know, just the eye test, I think we can safely conclude which version's closer to the real Magill. It's hard for me to conceive that they actually view him as a viable candidate for the Opening Day roster, which means they're gonna need to pass him through waivers one way or another. Why not just do it now and hang on to Curtiss?
This is what makes me think another MLB reliever signing has gotta be coming.
