Every Major League baseball team is part of a baseball club, which are made up of the team, the owner, and the team management. The owner might be an individual, a group, or a corporation. Club owners offer the money which a team needs to run. They work with the team management to organize activities such as running a stadium and selling tickets and concessions.
Club owners and management recruit players for the team. The complicated system of recruitment and payment of players is controlled by strict league rules, which involve the number of players clubs may have and the contracts, or agreements, that clubs and players sign. A union, called the Major League Players Association, advises players in these matters.
