I'm sorry but I have to use some serious sarcasm here: You're right, starting out in the bullpen just destroyed Chris Sale and Garrett Crochet. Oh my God! It ruined both of them and their careers!
I am surprised that so many people are against this. Do the fans here have no sense of history, no memory of Sale and Crochet? I've been thinking the Sox should move him up for the bullpen since watching him in the AFL. He is a strikeout machine, and since the Barons' playoff run and in the AFL, his walk problem has really improved (or become less bad).
Plus the White Sox really need help from the left side in the bullpen.
Plus, with a quality bullpen (Get a closer, Getz), I think there is a very real possibility that the White Sox will be competitive next year. (My definition of competitive is to win around 75 games and be able to claim you're in the hunt for the last wild card spot into early September)
Plus, I want to go one step further: After you put Hagen in the bullpen, now you can start working on making Grant Taylor the starter that he wants to be and should be.
Are we not worried about Taylor's psychological makeup at this point in his career? Only Hagen's?
