The original Harrisburg Senators played in the Eastern League in 1924. Playing its home games at Island Field, the team won the league championship in the 1927, 1928, and 1931 seasons. The Senators played a few more seasons before flood waters destroyed Island Field in 1936, effectively ending Eastern League participation for fifty-one years. In 1940, Harrisburg gained an Interstate League team affiliated with the Pittsburgh Pirates. However, the team remained in the city only until 1943, when it moved to nearby York and renamed the York Pirates. The current Harrisburg Senators won the Eastern League championship in the 1987, 1993, 1996, 1997, 1998, and 1999 seasons.
