Commissioner Bud Selig's special committee for on-field issues has talking about late-season roster expansion at length and there is increasing momentum to change the rules by next season, multiple industry sources have told Scott Miller of CBSSports.com. The current plan would still allow teams to expand rosters in the final month of the season but would require clubs to designate which players are eligible before each game.
The most popular scenario being discussed is to expand September rosters to 30, with each club's 25-man roster on August 31 being locked in throughout September. Locking in the rosters at the end of August would prevent teams from de-activating the starters not pitching in a particular game in order to load up with four additional minor leaguers.
Braves manager Fredi Gonzalez and Dodgers skipper Don Mattingly have both spoken out in favor of changes to the September roster rules. Angels manager Mike Scioscia, who is a member of Selig's committee, said that tweaking the rules would make sense "for a number of reasons".
