Tri-City Atoms Baseball Club: Welcome

About the Atoms: 

The Tri-City Atoms Baseball club plays in the Tri-City Adult Baseball League (TCABL). This is real baseball with uniforms, umpires, scorekeepers, and statistics. The TCABL formed in the early 1990's and is affiliated with the Men's Senior Baseball League (MSBL)

The TCABL is comprised of several teams made up primarily of players from Richland, Pasco, and Kennewick. The players are eighteen years of age and older with a median age of 28. Most of the TCABL regular season games are played at the Horn Rapids Baseball Complex. Each team plays a 18 game regular season schedule beginning in late May and the season concludes with playoffs in early August. The teams from the TCABL also play non-league games against teams from Yakima, Cheney, and other Pacific Northwest cities. Each year during Memorial Day Weekend, the TCABL hosts a tournament of teams from Seattle, Tacoma, Portland, and other locations. Teams from the TCABL often combine to play in tournaments in Boise (in April), Seattle (in July), and Portland (Labor Day Weekend). Most years, the league sends a team to Phoenix in October to play in the Senior League World Series against teams from all over the US (capturing the title in 2002 and placing second in 2008).
