If he gets called up in September, the team has to leave him down most of the way through May next year to push his free agency back a year. That will create a massive issue if he mashes in September, and then through spring next year. I don't see any reason at all to leave him down until September, and then call him up then. If they're f***ing around with service time, he stays down all year and comes up April 20th, 2019, or whatever the date is.
