List of Florida State League champions
The Florida State League of Minor League Baseball is one of three Class A-Advanced baseball leagues in the United States. The league was founded in 1919. A league champion is determined at the end of each season. Champions have been determined by postseason playoffs, winning the regular season pennant, or being declared champion by the league office. Off and on, the league recognized pennant winners and/or playoff winners as league champions. Currently, the first-half and second-half winners in each division compete in a best-of-three series to determin division champions. Then, the North and South division winners play a best-of-five series to determine a league champion. Since 1979, the winner of the League Championship Series has become the holder—until the following season's championship—of the Watson Spoelstra Florida State League Championship Trophy.
