ACTIVE MAJOR LEAGUE ROSTERS
The list below is for all active players on a Major League roster. During the season, the list should contain 25 active players except for September, when the list can be as high as 40 as rosters expand. During the off-season, all players on the 40-man roster are moved to the active roster. An age in a square indicates that today is the player's birthday. The position listed is the most recently played position in the Major Leagues (or Minors). The number at the right of each player is the player's current age.
