I was thinking about this yesterday. For as much as I hate the Personal Catcher™ concept, it might actually trap the Brewers into making the correct roster move when it comes time to decide between Nieves & Kottaras. Since Wolf really only likes throwing to Kottaras, I don't see how they keep Nieves. Even though Wolf pitched well with Lucroy behind the plate (though, it was the Pirates), he looked frustrated & annoyed numerous times on the mound, and obviously Roenicke had Kottaras catch him in his very next start. Even though the decision to keep Kottaras is correct in my mind based on other, more important, factors, I think what will ultimately seal the deal is the Wolf tie-in.
