Dirk Hayhurst is a journeyman pitcher and the author of Out of My League, about the year he broke into the majors with the Padres. It is also partly about porn, trannies, and failure, so in a way it's a story about all of us. Dirk is taking your questions down below. Be nice, read up on the dude if you haven't already, and for chrissake buy his book.
Update, 3:30 EST: Chat's over. Thanks, Dirk!
