Career
Medrano joined Alianza Reserves from San Luis Talpa Reserves in 2001 and was barely used for the seniors in the next season, prompting him to leave for Luis Ángel Firpo where he did get significant playing time. In 2010 he moved to Águila, but again he did not play regularly and joined Once Municipal for the 2011 Clausura, only for them to be relegated. Medrano made his debut for El Salvador in an August 2007 friendly match against Honduras, coming on as a substitute for Eliseo Quintanilla.
As of July 2011, he has not played any more internationals.
