MLB considering changes to roster expansion in Sept.

“Expanded late-season rosters have been a growing topic of discussion among members of Commissioner Bud Selig’s special committee for on-field issues. And there is increasing momentum to change the rules by next season,” according to Scott Miller of CBS Sports.

Miller says under the new rules, teams would be free to expand their rosters in September but would be limited as to who is eligible to play in a given game.

In addition, Miller says the new rules might allow rosters to only expand to 30 players, with the 25-man roster being locked in beginning on August 31 through the entire month of September – teams would be free to manipulate the final five players on the roster every day.

Miller the motivation to use the August 31 date as the base is to keep a team’s five-man rotation in place for the entire month of September as opposed to de-activating one or more of them in place of extra relievers on the expanded roster.
