Born in Portugalete, Biscay, Ríos started his career in his native Basque Country, representing two teams.
In 1958 he moved to Andalusia after signing with Real Betis, going on to play ten seasons with the club (nine in La Liga) before retiring in 1968 at 33; his debut in the top flight occurred on 21 September 1958 in a 4–2 win against Sevilla FC, in what was the first official match held at the Ramón Sánchez Pizjuán Stadium.

After one and a half campaigns with Deportivo de La Coruña in the second tier he was appointed at his former side Betis, being sacked on 30 November 1988 following a 6–2 away loss against Atlético Madrid, in a relegation-ending season;[4] he later worked with the club as director of football.
[5] Ríos' last job was with Rayo Vallecano (two seasons), being one of two managers in 1991–92 – the other was a young José Antonio Camacho – as the Madrid outskirts team returned to the top flight.
