The Seattle Mariners believe that all young athletes should have the opportunity to play baseball and softball regardless of the barriers they may face.
In 2018 the Mariners launched On BASE, a comprehensive youth baseball and softball initiative supporting young athletes ages 5-18. On BASE supports a network of coaches, athletes, and community members who collaborate together to increase access to safe, competitive, and positive playing experiences for young athletes across the Pacific Northwest.
In addition to existing youth baseball and softball programs, On BASE encompasses a variety of new efforts across the Northwest to address challenges young athletes face in their communities. On BASE provides grants for baseball and softball teams, training opportunities for youth coaches and young athletes, provides financial assistance to those who are not able to afford the cost to play, and more.
