The esteemed Rich Lederer asked if I'd be willing to do a guest post over at Baseball Analysts. I said sure, but (1) he must not make be analyze anything; and (2) I want two posts, because I lack the ability to edit myself. Rich, to the great detriment of the quality of his site, agreed.
Here's Part I of the two-part series. As you can see, I hijacked a ShysterBall title cliche for the post. That's how invasive species work, really. They get a toehold like that and before you know it, they've taken over.
Shhh! Don't tell Rich!
