The minor leagues are for learning what little gaps to exploit. Those gaps become fewer in number as they rise to the majors, but I want my players looking for them nonetheless. If you force it and the other guys don't make the play, that's something to remember. Later, as you move up, you force it and the other guys do make the play; you remember that too. Then, at the majors, you hopefully have learned what works and what doesn't. But, never losing that aggressive instinct is a good thing. I'm not going to second guess a play that worked, when it's in single-A.
