Our History

A lifelong baseball fan, Dave dreamed of seeing a minor league team, or its equivalent, playing games in his native Celina. So Dave wrote a letter, and the next day, Celina received a visit from Lou Laslo, commissioner of the three-year old Great Lakes Summer Collegiate League.Laslo liked what he saw, and in September of 1989, the Grand Lake franchise was born, beginning play in 1990, under the direction of the club’s first skipper, University of North Carolina assistant Mark Halvorsen. The team was part of an eight-team alignment in the GLSCL that included Toledo, Bowling Green, Sandusky and Lima in the North Division, and Grand Lake, Columbus, Cincinnati and Muncie in the South Division. Of the league members at the time of the Mariners’ start, only Lima remains, making Grand Lake the team with the second-longest tenure in the league.
