I'd say drop Hernandez, too, but all of these guys are worth a trade, unless you're in a 6 or 8 team league.
What's the deal with Beckett anyway? I have never hear of someone having so many problems with blisters! He had this last year, too! He's been pitching for what, 10 years? He hasn't been able to form calouses yet? Ridiculous!
I can handlle arm trouble, but blisters are too much.
As you can see, I have him on my roster too.
