According to MLB Trade Rumors’ Tim Dierkes, the cutoff for Super Two eligibility this year has been set at 2.116, meaning that any player who has accrued more than two years and 116 days of MLB service time as of the end of the 2021 season will be granted an extra year of arbitration in lieu of a minimum, team-controlled salary in 2022.
Going by the playing time on FanGraphs, this means that Cal Quantrill and Josh Naylor will be arbitration-eligible this year, while Myles Straw just narrowly missed with 2.112 years of accrued playing time and will be under team control for another year.
