OpenStreetMap
Per the suggestion of the opengeodata.org blog; I have taken-up the effort of updating and adding as much information as I can to Miller Park In Milwaukee (Home of the Brewers). This includes parking, pedestrian trails and walkways as well as some amenities that the stadium has to offer. Please feel free to update this info to make it more accurate!

Well, not the MLB, not even a avarage ballpark but the best we have. Not a lot of stuff beside the baselines so i did a little more infield work. Should be the right size feel free to copy it. ;-)

Very nice,
Thanks for sharing your work. I noticed there were not too many ballparks out there that were detailed. Really helps when visiting the parks though.
Thanks!
