What is the name of the championship trophy awarded to the World Series winner?

The championship trophy awarded to the World Series winner is the Commissioner's Trophy. Major League Baseball presents it to the team that wins the annual championship series between the American League and National League champions.

The trophy is presented by the commissioner of baseball, which explains its name. It is made of sterling silver and features baseballs representing the major leagues, with a design intended to symbolize the sport’s national championship. Each winning club receives a trophy to keep, while the names of champions are recorded as part of the trophy’s history.

The World Series began in 1903 and is generally played as a best-of-seven series. The winning team is the first to claim four games. The Commissioner's Trophy was first awarded after the 1967 World Series, when the St. Louis Cardinals defeated the Boston Red Sox.

It is often confused with the league championship trophies, such as the American League and National League pennants, or with trophies from other sports, including the Lombardi Trophy and Stanley Cup.
