I asked this in a couple other threads, but it is more appropriate here. What are the rules regarding option years, service time and FA eligibility, and how does the Jonathan Schoop situation fit into those rules? This is my understanding, someone please correct me if I'm wrong. Schoop had 4.027 years service time entering 2018, or 4 years + 27 days. He would need to be under 6 years after 2019 to control him through 2020. I don't know what he has left for options remaining but if he does have options he should indeed be able to be optioned. For simplicity, say the 2019 season starts on April 1st and ends September 30th. (183 days). A player needs 172 days on the MLB roster for a full credited season, so Schoop would need to be down until April 13th (from the beginning of the season) not to get a full year in 2019. Since he has an additional 27 days on top of 4 years, you would need to keep him down an additional 28 days after April 13th, or May 11th, 2019 being the hypothetical date you could keep Schoop down until to buy an additional service year in 2020. Should also note that this would be a pretty clear and deliberate manipulation of service time that would probably upset Schoop, his agent, and the MLBPA. Not going to speculate what more could come out of it then. EDIT: Correction on Schoop's ability to be optioned that I discussed in the 3rd paragraph. As of late August Schoop will hit 5 years service time and require consent to option him. So you could likely not plan to option him entering 2019. You would have to option him like right now, because they still can, and it seems they would have to keep him down 39 days to buy extra control in 2020. In other words, not happening.
