In the emotional times of September 2001 in New York City, following the September 11 attack on New York's World Trade Center, the Yankees defeated the Oakland A's three games to two in the ALDS, and then the Seattle Mariners, who had won 116 games, four games to one 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 1936–1939, 1949–1953, 1955–1958 and 1960–1964 as the only dynasties to reach at least four straight pennants. The Yankees had now won eleven consecutive postseason series over a four-year period. However, the Yankees lost the World Series in a dramatic 7 game series to the Arizona Diamondbacks, when Yankees star closer Mariano Rivera uncharacteristically lost the lead – and the Series – in the bottom of the ninth inning of the final game. With the loss, this marked the second time in five years that a team lost the World Series after taking a lead into the bottom of the ninth inning of Game 7 (following the Cleveland Indians in ) and the first time since that the home team won the seventh game of a World Series.
