The Oakland Athletics win their 20th consecutive game, an American League record, until the Cleveland Indians surpassed it in 2017.

The Oakland Athletics were an American Major League Baseball (MLB) team based in Oakland, California from 1968 to 2024. The Athletics were a member club of the American League (AL) West Division and played its home games at the Oakland Coliseum throughout their entire time in Oakland. The franchise's nine World Series championships, fifteen pennants, and seventeen division titles are the second-most in the AL after the New York Yankees.

The American League of Professional Baseball Clubs, known simply as the American League (AL), is the younger of two leagues constituting Major League Baseball (MLB) in the United States and Canada. It developed from the Western League, a minor league based in the Great Lakes states, which eventually aspired to major league status. It is sometimes called the Junior Circuit because it claimed Major League status for the 1901 season, 25 years after the formation of the National League.

The Cleveland Guardians are an American professional baseball team based in Cleveland. The Guardians compete in Major League Baseball (MLB) as a member club of the American League (AL) Central Division. Since 1994, the team has played its home games at Progressive Field. Since their establishment as a Major League franchise in 1901, the team has won 12 Central Division titles, six American League pennants, and two World Series championships. The team's World Series championship drought since 1948 is the longest active among all 30 current Major League teams. The team's name references the Guardians of Traffic, eight monolithic 1932 Art Deco sculptures by Henry Hering on the city's Hope Memorial Bridge, which is adjacent to Progressive Field. The team's mascot is named "Slider". The team's spring training facility is at Goodyear Ballpark in Goodyear, Arizona.
