Corrales became only the seventh person is Salvadoran league history to score 100 goals, a feat which has only been matched by Salvadoran greats Raúl Díaz Arce, Williams Reyes, Emiliano Pedrozo, Adonai Martínez, Hugo Coria and David Arnoldo Cabrera.
Corrales made his debut for El Salvador in a May 2001 UNCAF Nations Cup match against Nicaragua and has, as of December 2010, earned a total of 71 caps, scoring 16 goals.
The previous record was held by legendary Salvadoran striker Raúl Díaz Arce, who had scored four goals against Saint Vincent and the Grenadines in the 2002 World Cup qualifiers.
He scored his most memorable goal in a FIFA World Cup qualification match against Costa Rica on September 9, 2009.
Scoring a goal at the 90th minute that gave life back to El Salvador in this Qualification Stage.
