The 2004 Major League Baseball season ended when the Boston Red Sox defeated the St. Louis Cardinals in a four-game World Series sweep. The Red Sox championship ended an 86-year-long drought known as the Curse of the Bambino. The Red Sox were also the first team in MLB history and the third team from a major North American professional sports league ever to come back from a 3–0 postseason series deficit and win. This happened in the ALCS against the New York Yankees.
The Montreal Expos would play their last season in Montreal, before relocating to Washington DC, becoming the Washington Nationals in 2005.
