Thomas H. "Toad" Ramsey was an American Major League Baseball player who pitched in the majors from 1885 to 1890. Ramsey spent his entire career in the American Association, split between two different teams. He played for the Louisville Colonels and St. Louis Browns. He is sometimes credited with inventing a pitch, the knuckleball. He was one of the top pitchers in the Association for more than two years, with statistics that put him in the top five in multiple pitching categories.

The Louisville Colonels were a Major League Baseball team that also played in the American Association (AA) throughout that league's ten-year existence from 1882 until 1891. They were known as the Louisville Eclipse from 1882 to 1884, and as the Louisville Colonels from 1885 to 1891; the latter name derived from the historic title of the Kentucky Colonel. After the AA folded in 1891, the Colonels joined the National League and played through the 1899 season.
