Saucedo came to prominence playing for Club León of the Primera A in Mexico.

In his first season in the first division, Saucedo started all 17 games for Sinaloa, allowing 32 goals.

Following the 2006 Clausura season, Saucedo's team Dorados was relegated to the Mexican First Division "A".

He spent 3 "short" tournaments there before the 2008 Apertura when the arrival of Oscar Pérez prompted Saucedo's exit from the club.

Tigres loaned the goalkeeper to newly promoted Indios de Ciudad Juárez where he consolidated himself as a starter; he contributed to Indios' semi-final run of the Mexican championship, and more importantly staying at top flight of Mexican football.
