We are 2nd in the majors in innings by starting pitchers (Atlanta) and have 2 of the top 4 individually (Wheeler and Sanchez).
Obviously succes also dictates those stats, but we are not 2nd in ERA (5th) and having 2 of the top 4, one of which is a guy who probably should be more limited than being 4th in the league (Sanchez) does not say quick hook to me.
Odd stat, our starters are almost the worst in the league at HR/FB (13.9%). Is that just Walker screwing up the stats? Not sure, very odd. (Nola had that problem, but not nearly as bad this year). Maybe our collective 5th starter has skewed that stat?
