The Colorado Rockies are a Major League Baseball team based in Denver, Colorado.

Established in 1993, the Rockies play in the West Division of the National League.

The team is named after the Rocky Mountains, which pass through Colorado, just west of Denver.

The Rockies play their home games at Coors Field in downtown Denver.

Following multiple losing seasons, the Rockies won the National League pennant for the first time in franchise history during the 2007 season.

After previous failed attempts to bring the Major League Baseball to Colorado (most notably the Pittsburgh Pirates nearly relocating to Denver following the Pittsburgh drug trials in 1985), by the early 1990s a team seemed to be a possibility in Denver.

The Colorado Baseball Commission, led by banking executive Larry Varnell, was successful in getting Denver voters to approve a 0.1 percent sales tax to help finance a new baseball stadium.

Also, an advisory committee was formed in 1990 by then-Governor of Colorado Roy Romer to recruit an ownership group.

On July 5, 1991, the National League approved Denver and Miami, Florida, as the sites for two expansion teams to begin play in 1993.

The Rockies joined the National League in 1993, along with the Southern Florida franchise, the Florida Marlins.

The Rockies' first pick in the expansion draft was pitcher David Nied from the Atlanta Braves organization.

Major losses for the Colorado Rockies were all to free agency (second baseman Kaz Matsui went to the Houston Astros and pitcher Josh Fogg went to the Cincinnati Reds).
