Baseball players are professional athletes, but just because they get paid big money doesn't mean these guys can go out and run a marathon.
In fact, some baseball players are notorious for not taking good care of their bodies simply because they don't have to. Baseball isn't technically a contact sport, and if you're a good enough pitcher or hitter, it doesn't really matter if you can't field your position or win a foot race.
The players on this list aren't all oversized men who wouldn't know a diet if it hit them in the face (think Cecil Fielder or Babe Ruth). Some are well past their prime and can't move laterally or vertically. Others have too much body and not enough frame to support it.
Whatever the excuse, these 50 men are the least athletic players in baseball.
