How the World Series winner is decided
The World Series is the championship of Major League Baseball (MLB), contested between the American League champion and the National League champion. Each league crowns its champion via a postseason bracket (Wild Card Series, Division Series, Championship Series). The two league champions then meet in a best-of-seven series. The team that first wins four games claims the World Series title. Typically, the series runs into late October, though scheduling can shift due to playoffs and weather.
Key rules and tiebreakers
Games are played under standard MLB regular-season rules. If the series is tied after seven games, additional games are played until one team holds a lead of at least two wins after any completed game. The venue alternates between the two teams’ stadiums, with the higher-seeded team hosting more games in even-numbered series. There is no limit to the number of games beyond the minimum of four and maximum of seven needed to win the series.
