Born in Vigo, Galicia, Mariño played for Villarreal CF since the age of 14, having already represented four teams as a youth. He made his professional debuts in the 2010–11 season, helping the reserves barely avoid relegation from the second division while appearing in 38 games.
In the following campaign, Mariño was again first-choice, but as the main squad suffered relegation in La Liga, the B's were forced to drop down to the third level even though the team finished in a comfortable 12th position. After the departures of longtime incumbent Diego López and 41-year-old César (the latter retired), he was promoted to the first team by manager Julio Velázquez – also his boss in the second side.
Valladolid / Levante
On 5 July 2013, Mariño signed a five-year contract with Real Valladolid, with Villarreal retaining an option to buy him back for €300,000. He made his debut in the top flight on 17 August, in a 1–2 home loss against Athletic Bilbao.
In the tournament in Denmark, Mariño was a backup to Atlético Madrid's David de Gea as the nation won its third title in the category. The following year, he repeated the role for the under-23 team in a group stage exit at the Olympics in Great Britain.
