What is another word for reserve clause?
Pronunciation: [ɹɪsˈɜːv klˈɔːz] (IPA) 
The reserve clause, also known as the "reserve system," was a mechanism used by professional sports teams to maintain control over their players. This controversial practice was particularly prevalent in baseball during the early 20th century. The reserve clause stated that a team could maintain exclusive rights to a player for an indefinite period, effectively restricting the player's ability to negotiate with other teams. Synonyms for the reserve clause include the "reserve rule," "option clause," and "franchise tag." These terms are now largely obsolete, as modern labor laws have made the reserve clause illegal in most professional sports.
