In the American League, the New York Yankees returned for the eleventh straight year, the Boston Red Sox returned for the third year in a row, the now-Los Angeles Angels of Anaheim made their third appearance in the past four years, and the Chicago White Sox returned for the second time in six years.
In the National League, the Atlanta Braves made their fourteenth straight postseason appearance, the San Diego Padres returned for the first time since 1998, the St. Louis Cardinals returned for the fifth time in six years, and the Houston Astros returned for the third time in five years.
The postseason began on October 4, 2005, and ended on October 26, 2005, with the White Sox sweeping the Astros in the 2005 World Series. It was Chicago's first World Series title since 1917, which marked the end of the Curse of the Black Sox.
