That's an awful lot of introductory text! I wonder if you could manage to put some of it into dialogue or description later on, instead of at the front? I got a bit confused at first because I couldn't tell this was a parser game and was looking for a link to click.
That aside, this seemed fine otherwise but not for me--I am just not into baseball at all, and (despite the disclaimer) didn't quite understand what constituted a "pair" in this context, since I didn't really have the background knowledge for it. Sorry!
