The Horizon Air Summer Series is a season-long competition among teams comprised of some of today’s best college baseball players.

Fulfilling a mission of keen competition, the Horizon Air Summer Series crosses collegiate league boundaries to form a "league of leagues" made up of selected teams from throughout California and beyond.

Marysville, California is the Host City.

All Seasons RV Stadium is the Host Stadium.  

The intent is for the Horizon Air Summer Series to become increasingly competitive.  Teams that do not compete capably during a Horizon Air Summer Series season may not be invited back for a following season so as to allow entry to up and coming teams.
