At the end of each season, Major League clubs hold instructional league play, commonly known as instructs, an extended mini-camp that allows Minor Leaguers -- particularly those just starting their pro careers at the lower levels of their team's system -- to get some work in before calling it a year. Players work on specific parts of their game and get offseason workout plans while often playing a handful of games against nearby teams to provide low-key competition to put what they are working on into practice.
Here's a look at the Blue Jays roster, with the players' rank in the team's Top 30 Prospects list in parentheses:
