Real Madrid are a step into the Copa del Rey final, following a 3-0 win over arch rivals Atletico Madrid on Wednesday.
Pepe opened scoring for the Los Blancos when his effort was deflected off Emiliano Insua into the net.
Jese Rodriguez doubled the hosts’ lead from an Angel Di Maria clever pass before the Argentine forward’s shot deflected off Miranda past goalkeeper Thibault Courtois.
Atletico’s hitman Diego Costa, who posed a threat to Real’s defence on few occasions, was booked in the second-half and now misses the return leg. The Los Rojiblancos’ top goal scorer reacted to a challenge from Di Maria and earned a suspension.
Luka Modric denied the visitors an away goal, clearing off the line a Diego Godin goal-bound effort to help Iker Casillas maintain a club record eighth successive clean sheet. The Croatia international midfielder also came close through a well-struck volley early on in the encounter.
Real are likely to face Barcelona, who beat Real Sociedad 2-0 in their first-leg semis at the Nou Camp, in the final.
