Yankees vs Red Sox at Yankee Stadium September 24, 2010

In aftermath of the September 11 attacks, the Yankees defeated the Oakland A's in the ALDS, and the Seattle Mariners in the ALCS. By winning the pennant for a fourth straight year, the 1998–2001 Yankees joined the 1921–1924 New York Giants, and the Yankee teams of '36–'39, '49–'53, '55–'58 and '60–'64 as the only teams to win at least four straight pennants. The Yankees won eleven consecutive postseason series in this four-year period. In the World Series against the Arizona Diamondbacks, the Yankees lost the series when closer Mariano Rivera uncharacteristically blew a save in the bottom of the ninth inning of Game 7; all seven games were won by the home team.
