The league initially consisted of six teams based in Texas, Arizona and New Mexico: the Albuquerque Dukes, Douglas Miners, El Paso Mackmen, Las Cruces Farmers, Phoenix Senators and Tucson Old Pueblos.
For example, after its appearance in the Association, Phoenix and Tucson did not again have a professional team until 1928; El Paso until 1930; Albuquerque until 1932; Douglas until 1948 and Las Cruces until 2010.
The league officially started after a meeting held at the Hotel Sheldon, at El Paso, Texas, February 18, 1915.
[5][6] Nearly a month into the season, May 24, the Douglas and Las Cruces teams were dropped from the league due to financial difficulties.
They include Kitty Brashear, Frank Huelsman (who led the league with ten home runs), Rudy Kallio, Stoney McGlynn and Herb Hall.
