Walnut Youth Fastpitch Softball League (WYSA) has worked with young ladies in the City of Walnut and surrounding communities for over 50 years. Our established recreational softball league consists of a Board of Directors and ASA certified manager, coaches, and officials. Girls from ages 5-18 are invited to join a team sport that offers fun, exercise, and teamwork as it builds character through sportsmanship. (WYSA is an ASA-registered softball league)
