MLB Active Rosters Expand to 28 Players for September Stretch
Tap title to read story
Major League Baseball active rosters officially expanded from twenty six to twenty eight players across all organizations starting September first, two thousand twenty six. The roster limit permits a maximum of fourteen pitchers to be active for each club through the remainder of the regular season. This expansion gives franchises fresh flexibility during the final month of the playoff race. Teams contending for postseason berths can integrate reinforcements from Triple-A affiliates to manage player workloads, cover late-season injuries, and deploy specialized bench bats or relief arms. All active players on major league rosters as of midnight on September first become eligible for postseason play provided they were in the organization prior to the deadline. Organizations submitted their initial post-expansion roster filings to the league office ahead of the first games scheduled on the September calendar. Major League Baseball regulates these specific squad size adjustments annually under the current collective bargaining agreement provisions governing late-season roster management.
