Wikipedia - Harrisburg Senators

The Harrisburg Senators are a Minor League Baseball team who play in the Eastern League, and are the Double-A affiliate of the Washington Nationals. The team is based in Harrisburg, Pennsylvania, and play their home games at FNB Field on City Island, which opened in 1987 and has a seating capacity of 6,187.

The "Senators" nickname refers to the host city being the state's capital and thus home of the Pennsylvania legislature. The team colors are red, navy blue, gold, and white, the same of the parent club, the Washington Nationals.

Harrisburg has won nine Eastern League titles and is the first team in league history to win four titles in a row: 1987, 1993, 1996, 1997, 1998, and 1999. The 1993 Senators were recognized as one of the 100 greatest minor league teams of all time.
