Players typically must accrue three years of Major League service time -- with one year of service time equaling 172 days on the 25-man roster or the Major League disabled list -- to become eligible for salary arbitration. Super Two is a designation that allows a select group of players to become eligible for arbitration before reaching three years of service time.
To qualify for the Super Two designation, players must rank in the top 22 percent, in terms of service time, among those who have amassed between two and three years in the Majors. Typically, this applies to players who have two years and at least 130 days of service time, although the specific cutoff date varies on a year-to-year basis.
Dexter Fowler completed the 2011 season with two years and 168 days of Major League service time, which made him one of the leaders in service time among players who had between two and three years in the Majors. Thus, the outfielder qualified as a Super Two player and was eligible for arbitration. Fowler went through arbitration four times before reaching free agency following the 2015 season.
