Playing their first season in 1987, the Lima Blues finished third among the original six GLSCL teams.
In 1991, the Locos moved their home games from the campus of Ohio State University, Lima to the field at suburban Shawnee High School.
In 2008, the Locos worked out a long-term agreement with the City of Lima that allowed them to move the team back into the city limits to play their home games at Simmons Field.
Like other Summer Collegiate Baseball teams, the Lima Locos are dedicated to providing minor league level competition for NCAA players that wish to continue on into professional baseball.
The Locos operate in a similar manner to a Minor League team: playing nightly in stadiums before fans, using wood bats and minor league specification equipment, and experiencing road trips between games.
