Super-2 status has nothing to do with years of control, it's strictly a way to provide additional players access to arbitration as a reward spending a large amount of time in the majors, but not enough to be a full season. Two weeks in AAA is all that it takes for the team to gain a 7th year. Edit: It actually takes three weeks, not two. A Mauer-like player that comes up on day 1, and never goes down, would have 3 seasons at minimum, and 3 arbitration seasons. Year 1: minimum Year 2: minimum Year 3: minimum Year 4: arbitration Year 5: arbitration Year 6: arbitration A player that spends a couple of weeks (three) in the minors would end up with this... Year 1: minimum (just short of one full year of service) Year 2: minimum (just short of two years service) Year 3: minimum (just short of three years service, qualifies for super-2 arb) Year 4: arbitration Year 5: arbitration Year 6: arbitration Year 7: arbitration There are roughly 184 days in a ML season, it takes 172 days to acquire one year of service. Once 172 days are accrued in any one season the counting stops. As long as a player accrues fewer than those 172 days in any of their first 6 seasons, they require a 7th season to push them over the free agency threshold.
