Old Line Wiffle® Club was founded in 2020 for the purpose of playing competitive, fast pitch Wiffle® ball.

Club founder Brian Griffiths recruited Jim Braswell, Jeremy Davis, Craig Gajewski, and Scott Shaffer to form a team to play in the inaugural United Wiffle®ball 2020 National Championship Tournament in York, PA. After competing in this event, the founders decided to continue to play competitive Wiffle® ball and to grow the sport in Maryland.
