Building Community Through Baseball Since 1992

The Tri-City Adult Baseball League was established in 1992 by a dedicated group of local baseball enthusiasts aiming to create a competitive environment for adult players aged 17 and older. Founded in Richland, Washington, the league’s initial goal was to provide structured baseball opportunities for amateur athletes across South Eastern Washington.
