The 2009 Major League Baseball postseason ran from October 7 to November 4, 2009, featuring eight teams that qualified through division titles and wild cards. The New York Yankees ultimately triumphed, defeating the defending champion Philadelphia Phillies in the World Series to capture their 27th franchise title—a victory that remains the most recent championship for any New York City team. In the American League Division Series, the Yankees swept the Minnesota Twins, a series highlighted by a dramatic Game 2 walk-off home run from Mark Teixeira and the final MLB game ever played at the Hubert H. Humphrey Metrodome. Meanwhile, the Los Angeles Angels of Anaheim finally exorcised their postseason demons by sweeping the Boston Red Sox, marking their first playoff series win over Boston after four previous failures. The Minnesota Twins earned their spot only after winning a tiebreaker game against the Detroit Tigers on the last day of the regular season, while the Angels' sweep set up an ALCS matchup that ultimately led to the Yankees' championship run.
