Castellon took control early when Camara found the net at 6'10'', putting the away side 1-0 up in the first half. That proved to be the decisive moment, as Real Sociedad B could not find a reply before the break or after it.
The second half brought more disruption than goals. Jon Garro went into the book for the home side on 56'30'', before Diego Hernandez Barriuso and Adam Jakobsen were both cautioned for Castellon within the next three minutes. The visitors then began to manage the game through changes, with Antonio Gala and Inigo Cordoba introduced on 65 minutes, while Real Sociedad B responded with Arkaitz Mariezkurrena just after.
Further substitutions followed as Jon Eceizabarrena and Jon Balda arrived for the hosts in the 72nd minute, while Marc Olivier Doue and Hamza Bellari were sent on for Castellon after 77 minutes. Javier Soroeta and Ekain Orobengoa were also introduced late for Real Sociedad B, but the score did not move again.
Late cards for Inigo Cordoba, Unax Agote and Jari Vlak featured in the closing highlights, and the final stats confirmed a narrow away win. The result leaves Castellon top of the early standings on three points, while Real Sociedad B sit 22nd after one game.
