Born in Puerto de la Cruz, Province of Santa Cruz de Tenerife, Ratón finished his football formation at local CD Tenerife, playing his first years in the fourth division or lower and having also appeared for the club's B-team. He made his professional debuts in the 2002–03 season in the second level, aged 26.
After three seasons with Tenerife, Ratón moved to second-tier side Hércules CF, appearing very rarely through one sole campaign. He resumed his career in division three with Orihuela CF, and scored 21 goals in his second year, second overall in all four groups.
Ratón then had one assuming experience abroad, joining Greek team Iraklis Thessaloniki F.C. in the summer of 2008. He returned home after just one year with Girona FC, achieving, at the age of 33, his best season as a professional as the Catalans narrowly avoided relegation from the second tier.
