The Colorado Rockies are a professional baseball team based in Denver, Colorado. The team was established in 1993 as an expansion team, along with the Florida Marlins (now the Miami Marlins). The Rockies play in the National League West division of Major League Baseball (MLB). The team's home stadium is Coors Field, which is known for its high altitude and the resulting effect on the game, particularly on pitching. The Rockies have made the playoffs five times, including a National League Pennant in 2007, but have not yet won a World Series Championship. The team's colors are purple, black, and silver, and their logo features a mountain with a baseball inside a purple "C."
