Born in Cartaya, Province of Huelva, Marañón arrived at Sevilla FC at the age of 21, going on to spend two full seasons with its B-team. On 23 November 2003 he made his first appearance for the main squad, playing the entire match in a 0–1 away loss against RCD Espanyol; he played in another five La Liga games, notably a 1–5 defeat at Real Madrid.
In July 2004, Marañón joined Real Murcia, being an important defensive unit in his first two seasons, spent in Segunda División. However, he featured little as the club returned to the top level in 2007, and even less in the following campaign, being released in July 2009.
