What does the bold mean? That's a really odd way to put that. I'd guess it prevents them from scheduling a night game to complete the double header on days where there's a day game on the schedule already. That doesn't really make any sense and I can't imagine that this situation would ever come up. It seems pretty clear to me what it's saying. If the doubleheader was shceduled for a month from now you can use a 26th man, if it's a case like today's DH you can't. Assuming the basis for this is, so no one team is at a disadvantage should their AAA team be on the other side of the country with 12 hours to get the guy into town. I'm guessing Blake Parker got sent down and whoever reported it is off. It doesn't make sense for Rosscup to only be on the roster for the 2nd game. ETA: Muskat is the only one I see reporting it, so it's almost certainly wrong in some way.
