The MouseAbout Softball Tournament is more than just a competition it is a community driven effort to support those battling financial hardships due to cancer treatment. Since its inception in 2005 this annual event in Cle Elum, WA has honored the incredible legacy of Eileen "Mouse" Costello an accomplished athlete, devoted mentor, and compassionate advocate.

Join us in August 2025 to celebrate sportsmanship community and the power of giving back. Every game played is a step toward hope.
