As the offseason gets underway, players around baseball continue to elect minor league free agency.  While the threshold for big league free agency (six-plus years of Major League service time) is well known, there are several methods of qualifying for minor league free agency.  The most common criteria: players with 3+ years of MLB service time who have been outrighted off their teams’ 40-man rosters this season, players who have been outrighted off a 40-man roster multiple times in their career, or unsigned players not on a 40-man roster who have spent parts of at least seven seasons on a minor league roster or injured list.
