The problem is if its week 10 and he's still struggling then he shouldn't be the starter. Right now Blackburn should be starting and easing in Beason slowly. More importantly Beason is a MLB nothing more nothing less.
Beason deserves the benefit of the doubt. It varies though. If Beason is getting burned constantly then his starter status should be relinquished much earlier. Thus far, Jon has had one solid outing and one subpar outing. Therefore, it would be highly idiotic to pull him now based on a two-game sample size.
