i'm not sure if this has been posted somewhere else already, but baseball prospectus's entire site is free for this week. normally, most of their (excellent, imho) content is behind the subscription wall; subscriptions run about $5/month. one article that's up today is "future shock," a regular feature on the minor leagues, and today's gives an overview of the state of the nl systems. says nice things about ankiel and mather, and wonders if chris perez is ready right now. in addition, will carroll has been providing regular updates on chris carpenter in his fantastic "under the knife" injury column.
anyway, i don't have any connection to bp other than as a happy subscriber, but i'd encourage any/all of you to check it out.
