The Sun-Sentinel has put together a quiz in which you can test your ability to identify a Marlins player by their batting stance.
Test you knowledge on the subject but no fair cheating, which I think I did when I took the quiz. Oh, I did get a 100 for my efforts but as I said before, my results are a little bit tainted.
When you take the quiz just focus on the batting stance and nothing else and then you can say with pride: I named them all.
Good luck!
