Until this year, he has basically gone out 33 times a year, usually gone 6-7 innings and on average allowed 3-4 runs a game. In other words, he’s gone out and given his team a chance to win the game, which they have done 60% of the time. I’m not sure what you expect out of a guy who’s a #3/#4 starter.
Yes he has totally sucked this year; there is no sugarcoating that. Unlike you, I am not going sound tough by saying I’ll embarrass a guy by DFAing him in the middle of an inning. You want to totally lose a club and make sure no one ever wants to play in Boston again, be my guest and do it.
