Major League Baseball presented a series of proposals Thursday aimed at creating more roster stability, contingent on the players union agreeing to a salary cap and floor system, according to reporting from MLB.com and ESPN.

The proposals include requiring teams to set their 26-man active roster every Monday, with a window from the end of Sunday's game until Monday afternoon to make standard roster moves. Permitted exceptions would include injuries, bereavement and paternity absences, trades, and waiver claims. MLB also proposed changes to the current injured list minimum periods for position players, though reporting did not specify those details.

On the offseason calendar, ESPN reported that MLB has proposed limiting free agent signings to several weeks in December and then from early February onward each offseason. One source described this as a two- to three-week window for free agency. The proposal would also ban trades during the gap between these periods. Yahoo Sports characterized the free agency proposal as "radical," while reporting indicates the changes could speed up trade negotiations through the winter months. These proposals come as a potential work stoppage looms in baseball negotiations.
