Rounding Third

This is a five minute professionally done video that is available for free on our website (Click here to view) . It truly portrays the effect MSBL has had on adult baseball and how it allows our thousands of players each week to continue to play baseball, build new relationships, friendships and continue to “Live the Dream”.

Benefits of Membership

You can find a full list of league, team and individual benefits on our website (Click here to view) Besides the camaraderie and great friendships established, MSBL members enjoy discounts on products and services they can use for both their baseball and personal needs. Most players can easily recoup the cost of playing by leveraging the discounts each is afforded as a league member. In addition to participant legal liability insurance, local leagues can opt-in to our medical insurance. Should a player suffer a significant injury, this coverage supplements the player’s existing medical coverage and can be used to reimburse the player’s out of pocket expenses for deductibles, co-pays or instances where his personal insurance has limits (eg: physical therapy). With more employers transitioning to high deductible health care plans (HDHCP) this coverage provides peace of mind for players for very little cost. MSBL’s offered plans cannot be beat for price and coverage.

Benefits of Running a League

Local leagues also benefit with low cost, high quality insurance, baseballs, equipment and other items that come with MSBL’s reputation and buying power. By establishing long-term working relationships for the use of high school, college and municipal fields, the MSBL/MABL plays a constructive role in maintaining the fields that it uses. In addition, it involves its members in activities to support the baseball programs of the schools with which it works. MSBL’s logo can often be the difference between gaining the use of a baseball complex and getting the cold shoulder due to the lack of having the reputation of a top-notch nationally recognized leader in amateur sports. Leagues can also leverage their national clout to secure sponsorships. Packages are available to help leagues and teams secure sponsors.

Cost Facts

Unlike many sports that involve significant per player financial commitments, MSBL/MABL leagues work diligently to keep their costs affordable and competitive. Most leagues play approximately 20 games a season plus playoffs. When you break down the average cost per game, MSBL is a “win win” situation and allows players time for families as well as other fit and healthy life-styles activities. MSBL offers the oldest and most respected organization for your baseball investment.
