Ohio Cup
The Ohio Cup, also known as the Battle of Ohio and the Buckeye Series, is an annual interleague rivalry series between the two Major League Baseball (MLB) teams from the U.S. state of Ohio: the Cincinnati Reds of the National League (NL) and the Cleveland Guardians (formerly Indians) of the American League (AL). The series name comes from the trophy the teams play for, which was first introduced in 1989 for an annual pre-season exhibition game between the two teams, and later reintroduced in 2008.
