MADRID -- Alaves are back in the Copa del Rey semifinals after 13 years, advancing 2-0 on aggregate against second-division club Alcorcon after a scoreless home draw on Tuesday.
It is the fifth time Alaves has made it to the last four, but the first since their surprising run as a second-tier club in the 2003-04 season, when they were eliminated by eventual champion Real Zaragoza. They have never reached the final.
Alcorcon, making their debut in the quarterfinals, pressured from the start at Alaves' Mendizorroza Stadium but couldn't find the net to reverse the 2-0 home loss from last week.
On Wednesday, Real Madrid will attempt to overcome a 2-1 home loss to Celta Vigo, while Atletico Madrid will defend a 3-0 home win against Eibar.
On Thursday, two-time defending champion Barcelona host Real Sociedad after a 1-0 away win.
