This morning I launched a
minor league baseball thread, and along with it a new project to catalog and collect images for all documented and verified minor league baseball players. SABR has provided the background data for the project, including a database listing of minor league rosters which describe over 500,000 player/team combinations. If there is enough interest and participation, I will assemble a minor league facepack later this year.
Thanks to SABR for providing the player data for this project, and thanks to all who contribute!
