For Major League Baseball, each of the 30 franchises, including the Boston Red Sox and Chicago Cubs, fields nine players on the field during a game. This offers the best balance for competitive play. Their 40-man roster includes prospects.
TL;DR
Modern professional baseball teams typically carry 26 active players for standard games, though this number rises to 28 during the final month of the regular season. This roster size covers nine starters and a full bench of relief pitchers and substitute hitters. For youth or amateur leagues, teams often carry 12 to 15 players to ensure everyone gets playing time.
What Is the Standard MLB Roster Size?
An MLB team carries 26 active players on the roster from Opening Day through August 31, which must include a balance of position players and pitchers. These athletes are eligible to play in any given game, while the 40 man roster protects players from being drafted by other organisations.
Managers must navigate strict limits on how many pitchers they can carry at once. This prevents teams from using an endless stream of relief pitchers to stall the game. If a game goes into extra innings, these limits test the depth of the entire squad.

How Many Players Start on the Field?
Nine players take the field at the start of a defensive half inning, covering specific zones to prevent the opposing team from scoring runs. Each position requires unique physical skills, from the arm strength of an outfielder to the quick reflexes of a shortstop.
While nine players defend, the American and National Leagues both use a Designated Hitter (DH) to bat in place of the pitcher. This means ten players are usually involved in the starting lineup even if only nine play defense. Teams also keep a bench of "utility" players who can sub in for any position if an injury occurs or a tactical change is needed.
