There's no exact date. It's sort of complicated. (warning, this is all sort of gleaned from various web sites, and with baseball you never know if there aren't some secret rules they just haven't bothered to tell anyone about). Every day on the major league roster (or the DL) during the regular season = 1 day of service time. Rizzo already has 68 days of service time. 172 days of service time = 1 year. However, the major league season is always a little longer than 172 days. It can vary year to year, but the most common season configuration is 181 days long. So he can get 9 extra days, give or take, per season just by being on the roster all year long. If we don't want him to be a free agent after the offseason of 2017, we have to make sure he has less than 1032 (172x6) days of service going into that offseason. Or put another way, we don't want his current service time + his 2012 service time + his extra days to get to 172. If he gains 9 extra days of service time for each of the next 5 years, that's 45, plus the 68 he already has = 113. That means we could afford to use him for 58 days this season before it costs us a year of eligibility in the future. Realistically, he has to stay in the minors until mid-August to be sure of not gaining the extra year of service time. Okay so from a combination of what you said and other websites, is it June (68 days into the season) for team control through 2018 and late August to prevent him from being a super 2? How badly do we want to avoid Super 2 with Rizzo?
