Where's this proof you speak of? Just last year Cairo had a very respectable .742 OPS.
Ever think that a .188 BABIP might have something to do with his OPS this year? If it were anyone else, people would be screaming about how unlucky someone is with a .188 BABIP.
I don't consider that proof of anything. Guys that are still putting the ball in play regularly haven't "proven he's done."
