i've been wanting to post this thread for a while, but held off until the brewers got really close to being "in it". this is based on my understanding of postseason roster eligibility rules as of last year, so the rules may have changed. players had to active on the brewers 25-man roster as of 31 august in order to be eligible to play on a postseason roster. if they were on the disabled list as of 31 august (15-day or 60-day) and were activated at some point before the regular season ended, they were also eligible to be on the postseason roster. (for example, last season, both rickie weeks and carlos gomez came off the disabled list in september, and they were eligible for the postseason roster). if a player from the 31 august 25-man roster is injured and is unable to appear in a postseason series, another player within the organization as of 31 august is eligible to take his place. as of 31 august, the brewers had three players on the disabled list. the only one with a chance to return before season's end is alex gonzalez. that's my understanding of how postseason roster eligibility works. pretty simple. until you bring mark rogers into the equation. rogers was on the 25-man as of 31 august, and he's eligible to be on the brewers' postseason roster. i can't imagine that he would be included, unless they started stretching him out right now. let's assume that no other brewers are injured between now and the end of the regular season, and that corey hart returns to form. would the brewers have to put mark rogers on the disabled list if they wanted a 25th player on their postseason roster? would that replacement have to be one of the three (chris narveson, mat gamel or alex gonzalez) if one or more was able to be activated before the regular season ended, or could it be any player in the organization as of 31 august? this discussion could also apply to the nationals and their shutting down of stephen strasburg . . . but note that the nationals activated chien-ming wang from the disabled list this month (as well as mark derosa) so one of those two could take strasburg's spot. obviously, when the brewers decided to shut down mark rogers, 2012 postseason eligibility wasn't on their radar. this new wild card format is really going to force teams to rethink their roster planning for years to come.
