Major League Baseball Major League Baseball is the highest professional baseball league in the United States and Canada, comprising thirty franchises split between two leagues, the American League and the National League. The league traces organizational roots through the National Association of Professional Base Ball Players, the American Association (19th century), and the 1903 arrangement that followed the National Agreement (1903), evolving through labor disputes such as the 1919 Black Sox Scandal and collective bargaining episodes including the 1994–95 Major League Baseball strike. MLB governs competition, labor relations, and commercial rights across stadiums like Yankee Stadium, Fenway Park, and Rogers Centre.
History
Professional baseball development began with clubs such as the Cincinnati Red Stockings and leagues like the National Association of Professional Base Ball Players, leading to formation of the National League in 1876 and the American League in 1901. The 1903 World Series arrangement and the National Agreement (1903) created the two-league system, later reshaped by franchise moves involving the Brooklyn Dodgers to Los Angeles and the New York Giants to San Francisco. Key 20th-century events include the 1919 Black Sox Scandal, the rise of stars like Babe Ruth and teams such as the New York Yankees, integration initiated by Jackie Robinson after Branch Rickey signed him for the Brooklyn Dodgers, and expansion eras including additions like the Montreal Expos and Tampa Bay Rays. Labor history features the formation of the Major League Baseball Players Association under Marvin Miller, the 1975 World Series prominence, free agency after the Messersmith-McNally arbitration, and strikes affecting seasons in 1972, 1981, 1994–95, and work stoppages surrounding collective bargaining with commissioners including Bowie Kuhn and Bud Selig. 21st-century developments include steroid-era investigations such as the Mitchell Report, global talent influx from Dominican Republic and Japan, and franchise events like the relocation of the Montreal Expos to Washington, D.C. becoming the Washington Nationals.
Organization and Structure
MLB consists of two constituent leagues, the American League and the National League, each overseen by the Commissioner of Baseball and an executive office in New York City. Governance relies on the Major League Baseball Players Association for labor negotiations and mechanisms like the collective bargaining agreement to set terms for arbitration, free agency, and the luxury tax (officially the Competitive Balance Tax). Ownership groups include corporations, investment groups, and families such as the Steinbrenner family and entities like Fenway Sports Group. The sport interacts with developmental systems including Minor League Baseball, the Rule 5 draft, international signing processes in Dominican Republic and Venezuela, and governing bodies like the World Baseball Softball Confederation for international play at events like the World Baseball Classic.
Teams and Divisions
The thirty franchises are divided into the American League East, American League Central, American League West, National League East, National League Central, and National League West. Historic franchises include the Chicago Cubs, St. Louis Cardinals, and Boston Red Sox, while modern expansions brought teams such as the Arizona Diamondbacks and Tampa Bay Rays. Notable rivalries feature matchups like New York Yankees vs. Boston Red Sox, Los Angeles Dodgers vs. San Francisco Giants, and regional contests like Chicago White Sox vs. Chicago Cubs. Cross-border representation historically included the Montreal Expos and currently includes the Toronto Blue Jays.
Season Format and Playoffs
The regular season typically comprises 162 games per team, scheduled in divisions with interleague play introduced in 1997 after proposals involving the Designated hitter and earlier exhibition series such as the 1939 Major League Baseball All-Star Game. Postseason qualification uses division winners and wild cards determined by standings and tiebreakers, culminating in the League Division Series, League Championship Series, and the World Series. The postseason format has evolved with additions like extra wild-card games and expanded brackets similar to playoff changes in other North American leagues including the National Football League and National Basketball Association.
Rules and Gameplay
Gameplay follows rules codified in the official Baseball Rules enforced by umpires affiliated with organizations like the Major League Umpires Association and overseen by the league office. Distinctive rules include the designated hitter adoption differences between the American League and National League prior to universal DH adoption, the infield shift limitations resulting from recent rule changes, and pace-of-play initiatives such as pitch clocks and roster adjustments similar to experiments conducted in Nippon Professional Baseball. Scoring centers on runs produced by batting, pitching strategies including relief roles like the closer and setup man, defensive alignments, and statistical measurement systems such as sabermetrics advanced by proponents linked to the Oakland Athletics and analysts following methodologies from Bill James.
Players, Awards, and Records
Players form rosters constrained by options, arbitration eligibility, and service-time rules negotiated with the Major League Baseball Players Association; prominent players include Babe Ruth, Willie Mays, Hank Aaron, Barry Bonds, and contemporary stars like Mike Trout. Annual awards include the Most Valuable Player Award, Cy Young Award, Rookie of the Year Award, and the Manager of the Year Award, while honors such as the Baseball Hall of Fame in Cooperstown, New York recognize careers. Statistical records encompass milestones like Cal Ripken Jr.'s consecutive games, Nolan Ryan's career strikeouts, Pete Rose's hit record, and league leaders in categories tracked by organizations including Statcast and databases like Baseball-Reference.
Cultural Impact and Media Coverage
Baseball exerts cultural influence through literature, film, and media involving works such as The Natural, Field of Dreams, and authors like Roger Kahn and Dilip Saraf; broadcasting evolved from radio partnerships exemplified by the Mutual Broadcasting System to national television rights with networks like FOX, ESPN, and TBS. International outreach appears in events like the World Baseball Classic and exhibition tours to Japan and Korea Baseball Organization collaborations. Community engagement includes youth programs tied to organizations like Little League Baseball and philanthropic initiatives by players and ownerships, while controversies over labor disputes, performance-enhancing drugs, and stadium financing have intersected with political actors and municipal authorities such as the City of Chicago and New York City.
