Do you have any proof that Santana has an effect on Berrios? And, if so, that it is a positive one? Because Santana was on the team last year too, when Berrios was terrible. I'm not saying that he doesn't. But I don't know. And, not sure how you can know. Without any kind of evidence, that is no different than me saying that Berrios was terrible last year because of Santana. Correlation does not always mean causation.
