In the 2013 summer he returned to Recre and was assigned to the reserves in Tercera División. Domínguez was later called up to train with the main squad in late August. He made his league debut on 13 December of the following year, coming on as a late substitute for Jesús Vázquez in a 2–4 home loss against UD Las Palmas for the Segunda División championship.
On 22 March 2015 Domínguez scored his first professional goal, netting the last in a 1–1 away draw against Sporting de Gijón.
