Starting on September 18, eight Seattle Mariners will represent the Peoria Javelinas in the Arizona Fall League. They’ll have the highest number of players on a Javelinas team that includes prospects from the Red Sox, Pirates, Padres, and Astros’ systems.
The Arizona Fall League pits some of the best prospects in baseball against one another, as six teams comprised of players from five organizations each do battle over the course of a six-week season that includes championship and All-Star games. Some Mariners prospects, such as Art Warren and Evan White, have had great success there in recent years.
