According to CAA on Twitter (via MLBTR), the projected cutoff date for Super Two players is expected to be two years and 139 days.
This doesn’t really impact the Pittsburgh Pirates much. Neil Walker, who entered the year with one year and 166 days of service time, was always going to be a Super Two player. None of the other players on the roster were close to the Super Two cutoff.
Travis Snider started the year with two years and 15 days of service time. However, he spent so much time in the minors this year with Toronto that he will finish the season with two years and 91 days of service time.
Gaby Sanchez started the year with two years and 62 days of service time. However, he has enough service time this year that he will surpass three years of service, and will be arbitration eligible for the first time next season.
Using the 2.139 marker as a baseline for next year, the only player would be close to Super Two status after the 2013 season is Michael McKenry, who would have two years and 136 days if he remains on the active roster through the end of the 2013 season.
