Atletico reach final despite defeat
Atletico thrashed Racing 4-0 at the Calderon in last week's first leg but were rocked in only the second minute in Santander when defender Juan Valera headed into his own net from a corner.
Valera made amends six minutes later when he burst into the penalty area and pressured Jose Moraton into diverting a Jose Antonio Reyes free-kick past goalkeeper Mario Fernandez.
Atletico midfielder Jurado snuffed out any hopes of an unlikely Racing comeback shortly after half-time when he exchanged passes with Sergio Aguero and curled the ball into the bottom corner with the outside of his right foot.
Christian Fernandez was shown a straight red card with just over 20 minutes left after catching Atletico substitute Ibrahima Balde in the face with a forearm and late goals from Racing strikers Xisco and Mohamed Tchite were mere consolations.
Sevilla, the 2007 King's Cup winners, won last week's first leg at home to Getafe 2-0 and hung on to clinch a 2-1 aggregate win after losing 1-0 in Madrid on Wednesday.
