The Baltimore Orioles are an American professional baseball team based in Baltimore, Maryland, that competes in Major League Baseball (MLB). They are a member of the East Division of the American League (AL). One of the AL's eight charter franchises when the league was established in 1901 with President Ban Johnson; this particular franchise spent its first year as a major league club in Milwaukee, Wisconsin as the "Milwaukee Brewers" before moving to St. Louis, Missouri to become the "St. Louis Browns". After 52 often-beleaguered years in St. Louis, the franchise was purchased in November 1953 by Baltimore business interests led by Clarence Miles. The franchise officially moved to Baltimore for the 1954 season and adopted the historic "Orioles" name in honor of the official state bird of Maryland. The Orioles name had also been used by several previous major and minor league baseball clubs in Baltimore, including the franchise that would eventually become the New York Yankees. Nicknames for the team include the "O's" and the "Birds".

The Los Angeles Angels of Anaheim are an American professional baseball team based in Anaheim, California. The Angels compete in Major League Baseball (MLB) as a member club of the American League (AL) West division. The Angels have played home games at Angel Stadium of Anaheim since 1966. The "Angels" name was continued by team owner Gene Autry out of tribute for the Los Angeles Angels, a Minor League franchise in the Pacific Coast League (PCL), which played in South Central Los Angeles from 1903 to 1957. The current Major League franchise was established as an expansion team in 1961 by Autry, the team's first owner, who bought the rights to the Angels name from Walter O'Malley, the former Los Angeles Dodgers owner, who acquired the PCL franchise from Philip K. Wrigley, the owner of the Chicago Cubs at the time. In 2009, the Angels won the AL West division championship for the third straight season. 2013 was the fourth straight year in which the team did not qualify for the postseason, but marked the 11th straight year in which the Angels franchise drew more than 3 million fans in attendance, and made 30 seasons of at least 2 million fans in attendance.
