I found a similar thread on prosportsdaily.com forum page. I thought it was interesting and wouldn't mind seeing it started up on this site:
"Does anyone know of any good baseball fiction out there? I'm looking to expand my collection of the genre. Here are a few good ones to know about:
1. The Natural, Bernard Malamud - one of the most well written books in the genre. It is commonly studied in Literature Courses as high as graduate school. The book blows the movie out of the water!
2. Shoeless Joe, W.P. Kinsella - this is the book that Field of Dreams is based upon. It's an absolute must-read for baseball fans and those that are not illiterate.
3. In the Pen: A Baseball Collection, C.G. Morelli - this is a much more recent book. It's a collection of short stories with some really interesting perspectives on the game. I thought it was very cleverly written and wouldn't be surprised to see a few of the stories adapted for the big screen. Definitely check it out.
Please post any other baseball fiction books that you think are good reads."
