In the old days, teams throughout Major League Baseball could field a roster of 40 players in the majors once the calendar flipped to September. While the days of seeing every possible inch on the bench being filled are over, MLB teams are still able to bring up reinforcements for the final month of the year.
Rosters expand from 26 players to 28 men in September, so clubs will be able to call up two additional players for the final push. With minor-league seasons starting to wrap up in September, teams are willing to sacrifice minor-league success for major-league reinforcements.
