The History of the Colorado Rockies began in 1991 when a Major League Baseball (MLB) expansion franchise for Denver, Colorado was granted to an ownership group headed by John Antonucci. In 1993, the Colorado Rockies started play in the National League (NL) West division. Since that date, the Rockies have reached the MLB postseason four times, each time as the National League wild card team. Twice (1995 and 2009) they were eliminated in the first round of the playoffs. In 2007, the Rockies advanced all the way to the World Series, only to be swept by the Boston Red Sox.
