IMO, @wildcard, Means, Cobb, Wojo have more than a chance - they're pretty much locks. Same with Harvey, Bleier, Givens, Castro in the pen.
As bad as our pitchers are, there are some locks. I don't believe that the OD roster from a pitching perspective is as wide open as we'd like to think it is. How that plays out for the entire season is a different beast, for sure.
