The MSBL World Series, commonly referred to as World Series, is the west coast national tournament hosted by MSBL National.  This week long tournament began in 1988 making it the oldest MSBL national tournament.

The World Series takes place on the fields of the Cactus League spring training complexes in and around Phoenix Arizona.

Over the years the World Series has continued to grow not only in team numbers but also in draw of teams across the world. The MSBL World Series has reported regular attendance from serveral countries to include Canada, US Virgin Islands, Australia, Holland Peru, Purto Rico Venezuela. In recent year the first teams from Scotland have made the trek over the great pond and across the continent.

MSBL has continued to improve and add continued spice the World Series experience. Many games are brought live via radio and internet broadcasts.  Daily newsletters provide players with the status of the various games and teams. And sports trainers and massage therapists are brought in to provide some releif to the weary player. Finally each year a baseball trade show is attended by dozens of bat, glove, cleat, clothing and other companies each year providing member-players with equipment at typically unbeatable prices.
