In order for switch-hitting to be useful, Pena has to actually hit. It's not a useful attribute all by itself.
Ramiro Pena is a living stereotype, and every team in the league has a guy just like him. Some even have speed or some on base ability, but most, like Pena, do not.
Ramiro Pena is exactly the same kind of middling quality utility man with a great glove and no bat that you see on benches leaguewide. Most of them wind up as journeymen trying to steal big league playing time wherever they can find it from some team that has a hole at short. Some, like Yuniesky Betancourt, wind up starting and getting signed to ridiculous contracts because a team has a lack of options. Whether they get lucky enough to strike it rich with some desparate team or not, guys like Pena are a dime a dozen and are hardly anything the league hasn't seen before.
