New Player Request

Use the short form found on this page to request permanent placement on a MSBL team or to be placed in the Pool Player List. Pool Players are notified when teams are in need of temporary players for a game or two. Often MSBL Pool Players are asked to become a permanent member of that team or organization. The New Player Request form requires you to provide current contact information, positions played and any baseball experience if applicable. Please feel free to add any additional comments as well. Once the form is submitted an email will be sent to MSBL Administrator's to begin the placement process.
