That depends on what kind of team you are talking about.
There are around 25 players on both teams.
all teams have 25 players, except September where they can have up to 40
Teams can have about 25 players at one time though many keep 40+ players for injuries and such.
25 players - 8 position players, 5 starting roation, 7 bullpen, and 5 bench
During the regular season each of the 30 teams has 25 players. So the answer is 750.
25 man roster, 30 teams = 750 major leaguers at any given time
MLB rules state that there can be 25 active players on a team, in September teams are allowed to expand their rosters to 40 players
During Spring Training, there is no limit for how many players a Major League Baseball team can have but during the regular season all 30 teams will only have 25 players on their roster unless the 26th man rule is in event for a double header between two games. Starting on September 1st, teams can up players from their Minor League teams so that they can have a total of 40 players on their roster. During the Postseason only 25 players are allowed on a roster.
Aside from a Manager, there are 6 other coaches on a Major League Baseball team.
In Major League Baseball, teams may expand their active rosters to 40 players on Sept. 1, this includes for the playoffs as well. In the playoffs however you can only have 25 active players, the reason 40 players are on your roster is because unlike in the regular season you cannot move players to/from your minor league teams during the playoffs.
