#player-turnover

At any given moment during the baseball season between Opening Day and August 31, there are 780 active players on major league rosters - 30 clubs, each with 26 players. Maybe a few more are scattered about if the 27th Man clause is invoked for a day-night doubleheader or neutral-site contest. On September 1, when rosters expand to 28, the total rises to 840+. Given the steady stream of personnel promotions and corresponding demotions over the course of a campaign, it seems certain that MLB never encompasses the same 780 or 840 players from one day to the next. For example, the team we root for used 63 different players across 162 games in its most recent season, and activated two others who never saw action.
