Continuing a Fleischmanns Tradition Since 1895

Fashioned after the original team established in Griffin Corners, New York in 1895 by yeast magnates Julius and Max Fleischmann, the Mountain Athletic Club connects generations to the National pastime through authentic play according to the rules and customs of nineteenth-century base ball. 

The M.A.C. Grounds at Fleischmanns Park is listed on the

New York State & National Register of Historic Places.
