I'm pretty sure that you are not allowed wholesale call ups as in the past and are only alloewed one position player and one thrower.
Yep. One pitcher and one position player. Anyone else and you have to make a corresponding move on the 26 man roster.
Which is totally doable for this team. After the deadline, there is no reason that Rosario, Gallo, Winker, Williams, Finnegan, Harvey, Floro, or Law to be on the 26 man roster, thus freeing up their spots for call ups.
