Actually, no, all the information required is in the statement of the problem. I'd actually forgotten that there are no ties in baseball, and just reacted to the "Given that if A then B then which statements about A and B follow?" construction. So the question could've been about jai-lai or MTG or ... that game played in lunar gravity with lasers and mirrors that I've forgotten the name of ... or any other sport I don't know, and I would've gotten the same answer.
