Actually rule 40 now states Players who are on the 25-man roster, the major league DL, Suspend, Military, or the Bereavement List within a given organization on August 31 are eligible to be on that team's playoff roster. Other players are generally not eligible to be on the playoff roster. However, if a player in the organization is on the DL on August 31 and still on the DL at the end of the regular season, that player may be replaced on the playoff roster by any player that was in the organization as of August 31. Therefore it does not appear that the roster rules are as strict as they used to be. For example Chris Narveson is eligible to be on the playoff roster but will not be so a guy like Kintzler could be added since he was in the organization at August 31. Basically they can have whatever 25 man roster they want as long as they were with the organization at August 31.
