There are six teams in the Arizona Fall League: the Scottsdale Scorpions, Mesa Solar Sox, Peoria Saguaros, Phoenix Desert Dogs, Peoria Javelinas and Surprise Rafters. These club names were picked by Major League Baseball as reflective of the Southwestern desert traditions in the state.
The teams are broken into two divisions, East and West. Each Major League Baseball team sends six top prospects to the Arizona Fall League, 180 players in all. The games are played in the Spring Training stadiums used by the Giants, Mariners, Padres, Cubs, A's, Royals and Rangers.
The league features many of the nation’s top-rated major league prospects. Games are played during the months of October and November. The Mesa Solar Sox play at HoHoKam Stadium in Mesa.
