New York Yankees, American professional baseball team based in the borough of the Bronx in New York City. One of the most famous and successful franchises in all of sports, the Yankees have won a record 27 World Series titles and 41 American League (AL) pennants.The franchise began in 1901 in Baltimore, Maryland, competing as the Orioles in the AL for two seasons. The struggling Baltimore team was bought by Frank Farrell and Bill Devery in 1903 and taken to New York, initially to Hilltop Park (1903–12), one of Manhattan’s highest points, which led to the name New York Highlanders. Local sportswriters often referred to the team as “Yankees” or “Yanks,” because the team was in the American League.After the club moved to the Polo Grounds in 1913, the name Highlanders fell further into disuse, and the team was officially renamed the Yankees. The team has also been called the Bronx Bombers, the Pinstripers (due to the distinctive pinstripes on their home uniforms), and the Evil Empire (by opposing fans, particularly those of their archrival, the Boston Red Sox). They played at the Polo Grounds until 1922 and then moved to Yankee Stadium (“The House that Ruth Built,” nicknamed after famed Yankees slugger Babe Ruth), where they played from 1923 to 2008. The team moved to a new ballpark, also named Yankee Stadium, in 2009.The team was not a regular pennant contender during its first 18 years in New York. Its fortunes changed completely in 1920, however, with the acquisition of Ruth from the Red Sox for cash and a loan against Boston’s Fenway Park—the most famous sale in baseball history. With the superstar pitcher-turned-outfielder leading the charge, the Yankees dynasty began to take shape during his second season with the team. It won three consecutive AL championships and the team’s first World Series title (1923).The team was not a regular pennant contender during its first 18 years in New York.
