In June, the provincial superior, Joseph de Utrera, reassigned Espinosa to Mission San Xavier del Bac.
The residence there was not yet complete, so Espinosa relocated temporarily to the nearby Mission Los Santos Ángeles de Guevavi.
[2] Early in 1756, Espinosa moved into the mission in Bac, where he attempted to suppress native rituals involving ceremonial dance and intoxication.
[2][1] Subsequently, Governor Juan Antonio de Mendoza [es] and Captain Francisco Elías Gonzalez led a punitive expedition, which reinstalled Espinosa at Bac and fought Jabanimó by the Gila River.
Espinosa was too sick to be moved, and spent another year assisting Neve after recovering, but eventually he went on to serve at Mission Los Siete Príncipes del Átil.
