Diaz, from Napa Valley, Calif., was invited to camp after excelling at the recently completed Rapids tryout combine. After two years playing at St. Mary's College, Diaz moved to Europe to pursue his professional dream. He has played in England, Hungary, Germany, Finland, Brazil, and W Connection in Trinidad & Tobago.

Romero was a member of the U.S. U15, U16, and U18 teams while Diaz reached the U.S. U-20 level.

One player that is no longer in camp is former FC Dallas forward Ruben Luna, who informed Rapids coach Oscar Pareja that he was presented with a chance to pursue an opportunity in another league,
