Defining the World Series
The World Series is the annual championship tournament between the American League (AL) and National League (NL) champions in Major League Baseball. The modern format pairs the winners of the AL Championship Series (ALCS) and the National League Championship Series (NLCS), each a best-of-seven playoff. The victor is decided through a best-of-seven series, with home-field advantage awarded to the team from the league that wins the All-Star Game, or, since 2022, the team with the better regular-season record.
Key Structural Elements
- Format: Best-of-seven contest between league pennant winners.
- Home-field advantage: Awarded based on regular-season record since 2022.
- Designation: Officially known as the "Fall Classic" and branded as the "World Series of Baseball."
