Prospects have been working out for more than a year at clubs' alternate training locations, extended spring training sites, and/or at their homes. Some players have thrived, while others... well, we don't know. They haven't played a game yet anyway. As far as I'm aware, there is no standard schedule for these workouts. Some teams may only have one or two of them per year, while others might have five or six. It's pretty much up to the individual club.'s scouting staff when and where they want their prospect to train. Teams use the information they gather from these sessions to help determine how their players stack up against other organizations', let alone individuals'. A lot can change in a year, especially with young players who are just beginning to explore their options. However, based on past performance, these events tend to have more of an impact on draft position than on player development.
