Seattle, Portland, Oregon, San Diego and Minneapolis-Saint Paul. These clubs are different from older clubs in that they consist of predominantly American-born players who bring a new dimension to the game and actively seek to promote it as a mainstream sport. On 31 January 2009, the first ever game of hurling to be played between two American collegiate hurling teams took place at Stanford University, California, when the Stanford team took on their rivals from UC Berkeley in a challenge game. This game was organized by the California Collegiate Gaelic Athletic Association, which is recognized by the Western Division Board as the authority for hurling teams at third level education colleges in the area. Cal won the challenge game by 3–10 to 3–9. The two teams then played a two-game aggregate series for the inaugural CCGAA Gary Duffin Memorial Cup. Stanford won the championship- the first ever collegiate cup competition in North America- winning the first match 2–10 to 1–7 on February 21, 2009, and then winning the second match 6–9 to 1–11 on April 18, 2009. Both matches were played at Páirc na nGael on Treasure Island in the middle of the San Francisco Bay. The U.S. national collegiate hurling championship has been running since 2011.

Under Bulfin's patronage, the Argentine Hurling Club was formed on 15 July 1900. On 17 August 1900, Bulfin printed the rules and a diagram of a hurling pitch in The Southern Cross, the official newspaper of the Argentina's Irish community. Enthusiasm spread rapidly and teams were quickly established in both the neighborhoods of Buenos Aires and the surrounding farming communities. The Passionist and Pallotine Orders took a major role in promoting the game. Games of hurling were played every weekend until 1914 and received frequent coverage even from Argentina's Spanish language newspapers like La Nacion. After the outbreak of World War I, however, it became almost impossible to obtain hurleys from Ireland. An attempt was made to use native Argentine mountain ash, but
