The Super 2 players for the Yankees are Gleyber Torres, Luke Voit & Clint Frazier with Miguel Andujar missing by days. This will cost the Yankees as contracts will not just be the minimal raise- not quite sure how it works but here is the definition of a SUPER TWO accorindg to MLB:
Super Two
Definition
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 injured 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.
