Check out this ESPN story about 13 yr old Chelesa Baker a little league pitcher. She hasn't lost a game in four years. Joe Niekro (who pitched in the majors) taught her to throw the knuckleball. It's a wonderful and inspiring story.
If you missed it check out the baseball feature I did with nine authors, especially if you are looking for some really good baseball books. One of the things I love about that line up is the gender balance. Seven out of the nine books have female characters who love the game of baseball, either as fans or players.
