Player Development

The Arizona Fall Instructional League, often nicknamed "Instructs," is a short camp usually held in September at the Peoria Sports Complex. It is considered a teaching camp and the goal is to refine the baseball skills of young players and prospects under the close watch of an organization's coaching, scouting and training staff. Rosters are determined by the front office and typically include the most highly-regarded prospects from the lower levels of the system.

Approximately 45 lower-level baseball players and younger prospects are invited to participate each year. Others players who are commonly invited include Class A-level players who missed significant time in the recently completed season, players who are rehabbing from injuries, players who are prepping for the Arizona Fall League and raw players who are learning a new position or focusing on the development of a specific skill.

A typical day includes drill work in the morning, lunch and then an afternoon game. The games are controlled and allow for players to continue to work on specific skill development. A significant portion of the player development executive staff attend each year to examine their prospects.

Game, scrimmage and practice schedules are frequently subject to change by the player development staff of the Seattle Mariners and San Diego Padres and cannot be provided by Peoria Sports Complex.
