The Miamisburg Baseball & Softball League was formed in 2017 by the City of Miamisburg Parks and Recreation Department to meet the need for a recreational baseball and softball organization within the Miamisburg community. Since its inception, the league has grown to be the home for over 600 players annually!

MBSL is very proud to be the youth recreation provider for young Miamisburg athletes! Our MBSL opportunities consist of both spring and fall leagues for baseball and softball while offering various clinics and programs for players and community members throughout the year.

Who Are We

The vision of the Miamisburg Baseball & Softball League is to be the premier provider of youth recreational baseball and softball in the South Dayton Area.

The mission of MBSL is to provide quality baseball and softball opportunities with a focus on player development, team experience, teaching the importance of sportsmanship, and fostering the love of the game while preserving the recreation program participation at the historic Rice Field.

  • MBSL will be a quality resource for individual player development for both skills and emotional wellbeing.
  • MBSL will provide the opportunity for the community to participate in the team atmosphere. Healthy team dynamics will be promoted to foster sportsmanship, comradery, and community within the MBSL League and Miamisburg Community at large.
  • Operational and financial planning will emphasize the sustainability and quality of the program and preservation of Rice Field for future generations of players.
