Chart: Patience required for Rule 5 draftees

The Rule 5 draft for minor leaguers takes place every offseason. Players have to spend a full season in the major leagues or be offered to their former teams for $25,000. Since 1985, the Twins have kept four Rule 5 draftees for a full season; what they did their first year and how their Twins careers turned out:
