I'd rather have Beckett. He's only 24 and he doesn't have control problems, he plays on a good team, was an uber-prospect coming up through the minors. Perez has horrible control, is on a bad team, and has a body type/mechanics that will most likely result in some kind of arm injury. In my opinion, Perez has about the same chance of being injured as Beckett, but usually arm injuries will hold a pitcher out of action longer than blisters. Plus overall, Beckett is just the better pitcher. In fact, it's not even close. I have no idea why Perez is going before Beckett in leagues, especially keepers.
