The 1921New York Yankees season was the 19th season for the Yankees. The team finished with a record of 98–55, winning their first pennant in franchise history, winning theAmerican League by 41⁄2 games over the previous year's champion, theCleveland Indians. New York was managed byMiller Huggins. Their home games were played at thePolo Grounds.
With star sluggerBabe Ruth hitting 59 home runs, setting a new major league home run record for the third consecutive year, while also having his greatest overall season statistically, the Yankees appeared to be the team to beat in theWorld Series. Their landlords, theNew York Giants, had rebuilt after slipping a bit in the late 1910s, and had won theNational League pennant. For the first time, all the games of a World Series would be held in the same ballpark, thePolo Grounds. The best-5-of-9 Series (its last before returning to the best-4-of-7 format) saw the Yankees take a 2 games to 0 lead and later a 3–2 series lead, but Ruth suffered a serious injury in game 3 that limited his appearances in the remaining games, save for one pinch-hit appearance, and the Giants rallied to win the Series 5 games to 3.
