important to note: a player optioned must stay in the minor leagues for at least 10 days(unless recalled to replace an injured player or player put on the paternity / bereavement list), or until the conclusion of that club's minor league season--whichever comes first. the minor league season ends 3 september, so as of yesterday's optioning of zach davies and corey knebel, the requisite 10 days would occur first. however, if the brewers option more players in the coming days, they need to factor that the biloxi shuckers are postseason-bound, which extends their season. the sky sox are in the hunt for the postseason. the timber rattlers are likely not post-season bound. thus, if more players are going to be optioned before the end of august, you'll likely see them optioned to the timber rattlers, as their season will most likely end 3 september.
