The first AAABA team from Cleveland competed in the 1946 tournament in Washington, DC. The team won its first two games on the field (New Orleans 7-2 and Nassua 2-1) but both wins were negated when it was discovered that the team played with inelligible players. As a result, the team was eliminated 0-2 and Cleveland did not return the following year.
In 1981, the city of Cleveland return to the AAABA represented by Chuck Rozanski and the Mill-Rose team. The went 1-2 in the Zanesville regional with a win over Dayton. The city made its first appearance in Johnstown in 1982 and finished in 7th place with a 2-2 record. Their first win was an 8-3 victory over host Johnstown. Cleveland won at least 1 game in their first 5 tournament appearances, but were winless in 4 of the final 5 tournaments between 1989 and 1995.
After a 10 year lapse, Cleveland returned to the AAABA in 2006 but was represented by the Allegheny Athletics from Pittsburgh, Pennsylvania. The Athletics swept the Zanesville regional and finished 2-2 in the national tournament. Their wins came against Livonia and Brooklyn, and loses to eventual champion Baltimore and eventual runner-up Chicago-Metro. The next four seasons were less successful, as Cleveland managed only 1 win in 3 tournament appearances and finished in last place in 2010.
After the lackluster 2010 showing, Cleveland turned heads in 2011 by sweeping through the Altoona regional with wins against Schenectady, Altoona, and two mercy-rule wins over Buffalo. Don Navatsyk's Chardon Blizzard club continued their surprising run with a 4th place, 3-2 showing at the national tournament, which was the best showing of any Cleveland franchise. Their wins included an 8-6 win against Johnstown and a 6-5 10th inning win over Altoona. Their loses came to finalists Baltimore and New Orleans.
The 2012 tournament was the most successful for the Cleveland franchise, as the Blizzard won their first 5 games before dropping the final 2 to eventual-champion New Brunswick.
