Sometimes I wonder, and this is in general, why a HC will stick with a stud who is struggling when at a high pitch count and control and velocity going out the window. Does he really expect the starter will get a "second wind." Pretty sure that never happens. If the next available pitcher is fresh and even 75% of what the ailing starter can do when 100%, then why not put him in to avoid arm injury for the starter. I always ask myself "do you have NOBODY on the bench or what?"
