Major League Baseball operates as the preeminent professional North American baseball organization, dividing its 30 member clubs equally between the National League and the American League. According to league structure and historical records, the competition anchors a vast calendar encompassing a 162-game regular season followed by an extensive postseason tournament culminating in the World Series each autumn.
Structure of the National League and American League
The league system splits evenly into two distinct bodies, each featuring 15 teams divided geographically into East, Central, and West divisions. According to official league historical data, the American League and National League operated as independent corporate entities until formally unifying under a single organizational structure in the year 2000 under the Office of the Commissioner of Baseball. Teams play the majority of their schedules against divisional opponents while maintaining regular interleague matchups across the summer months.
Regular Season Schedule and Divisional Play
Clubs navigate a grueling 162-game regular season running from late March or early April through late September or early October. According to MLB scheduling parameters, travel logistics require clubs to manage rigorous time zone changes across the United States and Canada. Teams compete to capture divisional crowns or secure one of the available wild card berths to advance toward the World Series championship.
Postseason Format and World Series Qualification
The postseason bracket accommodates twelve teams in total, featuring division winners and wild card qualifiers from both the American League and the National League. According to league postseason rules, the tournament progresses through the Wild Card Series, Division Series, and League Championship Series before the two pennant winners clash in the best-of-seven World Series.
