The notion that Mark Connor resigned as Orioles pitching coach on Monday because of the struggles of some of his pitchers doesn't make any sense to me. Connor has been a great pitching coach for a long time, and you don't get to be that by getting frustrated when things don't go well. You get to be that by helping guys correct the problems that keep them from having success.
Connor apparently told manager Buck Showalter that he just couldn't grind out another long season and give the effort the job deserves. I don't see any reason to doubt that, though I can see why somebody could look in from the outside and wonder if he just got tired of the uphill battle he had been fighting with this inconsistent pitching staff.
