The Clearwater Threshers are the High-A minor league affiliates of the Phillies, and are located at the same place where Phillies fans travel every February and March to enjoy spring training. They have been affiliated with the Phillies since their very first season of existence all the way back in 1985.
For their first 29 seasons the club was known as the Clearwater Phillies and played their home games at old Jack Russell Stadium. With the opening of a new ballpark now known as Spectrum Field in 2004, the team name and identity was changed as well.
