Historically, winning the first game of a World Series has helped almost two-thirds of the teams competing go on to win the best-of-seven contest.

The annual championship series of Major League Baseball in the United States and Canada, the World Series concludes a postseason that includes playoffs between divisional champions.

First played in 1903, the World Series championship is determined through a best-of-seven playoff and is a contest between the champions of baseball's National League and American League.

In the 2023 World Series, the Texas Rangers prevailed over the Arizona Diamondbacks.

Often referred to as the "Fall Classic", the World Series has been played every year since 1903 except in 1904, when the National League champion New York Giants declined to play the American League champion, the Boston Americans. It was also canceled in 1994 due to a strike.

The World Series is a best-of-seven series, with the championship going to the first team to win four games.

The home field advantage (games 1,2,6,7) is determined by which league wins the All-Star game in July, with Game One played on the home field of that league’s champion. Games 3,4,5 are consequently played on the home field of the opposing league’s champion.
