I've been checking around and having a hard time finding out for sure.
Best I can find, pinnacle says game 163 doesn't count toward grading season win totals. But I don't know if that's a policy unique to them, or if it's a general rule across multiple books, Vegas, etc.
Anyone know?

Reason I ask is that I've run a pool at work this season and need to know how to deal with the possibility of NYY playing Baltimore in a tiebreaker. NYY might end up very close to the total, and a 163rd game might mean the difference.
