Some time ago, Marlins closer Leo Nunez was arrested in the Dominican Republic for using a false identity. He was found out to be Juan Carlos Oviedo. Thursday, Indians starter Fausto Carmona was arrested in the Dominican Republic for using a false identity. He was found out to be Roberto Hernandez Heredia.
Two random points, or tip of the proverbial iceberg? Let's ask Baseball America's Ben Badler:
Not surprised about Fausto Carmona being older. I've heard that from DR folks in the past. Just surprised he got caught.
People who know how papers get manipulated in the DR are afraid this could get ugly. Don't be surprised to hear another big name caught.
That isn't a vague allusion to a specific player. There is no specific player that Badler has in mind. It's just that, hey, don't be surprised. This happens. It has happened more times than we know, so far. More cases could be discovered, and some of those cases might involve big-name players.
Who are some potential candidates? Let's consult the Baseball-Reference list of players born in the Dominican, and take the actives:
...you know what, actually, let's not do this. You can go over the list on your own.
