It would have taken quite a situation to put Fister on the bases. For one, the Tigers are carrying a pinch-running specialist on their bench in rookie infielder Hernan Perez. For another, most of the players the Tigers would pinch-run for are the same players they would keep in the game in extra innings for their bats.
Still, it's an idea worth stowing away for future reference, especially if the Tigers advance to the World Series and lose the designated hitter under National League rules.
Fister has never appeared in a game as a pinch-runner, but he's 4-for-15 as a hitter, so he knows his way around the bases.
