I don't have a problem with having three catchers on the roster, but I don't see the advantage to having three of Lucroy, Zaun, Kottaras, and Rivera on the roster. I guess for the most part I just don't think Rivera swings a bat well enough to justify giving him pinch hit plate appearances, and most definitely does not hit well enough to give opportunities at first base. If he were the Brewers' best option as a RH bench bat, then I could understand having him as a third catcher, but he isn't. I'm not a huge Adam Heether fan like some are, but his numbers in AAA are much better than Rivera's, and his MLB equivalencies are far better than Rivera's major league numbers. As for the argument of having a 3rd catcher to give the team flexibility, I guess I don't buy it for teams who have an emergency catcher. Consider the situations where the Brewers either pinch hit or pinch run for Zaun. Say this happens 25 times over the course of the season (yes, I am being generous). Assume Lucroy subs in for him at catcher. These situations would probably add up to 100 or so innings of Lucroy subbing, without an official catcher backing him up. If Lucroy were to get hurt, and the Brewers were to bring in McGehee as emergency catcher, he would see what, 3 innings at most per time Lucroy got hurt? By the next game, they could have Rivera up from Nashville anyways.
