Profiting from injury to Andrés Palop, Beto made his debut with the Andalusians one day after arriving, starting in a 1–2 away loss against Atlético Madrid in the first leg of the semi-finals of the Copa del Rey, with his team playing the last eight minutes with only nine players. His first La Liga match came on 3 February 2013, in a 2–1 home win over Rayo Vallecano.
