I don't know if this is a new feature or not, but I was alerted to it from a blog post on the MLBlogs network. The teams provide a link to the media information provided by teams on gameday. The info opens in a viewer on the web page and if you click the Print icon a PDF opens in a new window. 

The info provided is fairly trivial and available from various places, but there's info on upcoming starters for games, TV & radio broadcasts and other tidbits. Unfortunately there doesn't appear to be a RSS feed for it. 

You can click on the Gameday Press Pass to see links to all MLB teams.
