Nope, it's the 25-man roster, not the 40-man. The only way another player can be added from your own system is if a player is on the DL and will miss the playoff series (and, of course, the player has to be in your system when that roster is set on Aug. 31). I don't think you're right....or if you are, then ms muskrats article was wrong on cubs.com (which wouldn't surprise me). You have the link? It's definitely 25-man + DLed players. Couldn't find the link, but I found this one: http://www.bostonherald.com/sports/baseball/red_sox/view.bg?articleid=1018841 Sounds like the rule changed this year.
