These are Pagnozzi's numbers. He doesn't really hit much and isn't young, but I'm guessing the Pirates are trying to give themselves some flexibility this offseason in case they're unable to pick up another catcher to replace Ryan Doumit or Chris Snyder (or to bring back Doumit or Snyder). That said, it doesn't look like Pagnozzi would be much of a complement to Michael McKenry, who also can't really hit. I'm not really sure why Pagnozzi would be on anyone's 40-man roster, and my initial thought was that the Pirates were going to try to sneak him through waivers themselves, but that doesn't make sense, because he would become a minor-league free agent if they did.
By the way, I don't think this is a Clint Hurdle production. Pagnozzi was in the Cardinals organization (and he's the nephew of Tom Pagnozzi, by the way) until this year. So ... yeah. I have no idea what the explanation for this move is. Not that it's a huge deal either way, but as WTM points out in the comments, the last thing the Pirates need right now is yet another player who can't hit.
