"The Arizona Historical Society's museum at Papago Park has a great new exhibit on the history of baseball in Arizona and the formation of the Cactus League. It shows how baseball came to Arizona in 1874 and that by the late 19th century, it was popular in frontier outposts like Fort Huachuca, near the Mexican border." - from an article in the March 4, 2011 Orange County Register

Arizona has become increasingly popular over the decades as a place for major league teams to go for spring training and today fully half of major league teams play their pre-season games in the Cactus League.
