BARCELONA, Spain (AP) -- Atletico Madrid drew 1-1 at Real Betis on Thursday to ease into the Copa del Rey semifinals with a 3-1 win on aggregate.
With striker Radamel Falcao out through injury, forward Diego Costa crushed Betis' hopes of advancing when he pounced on a defensive error just before the break in the second leg match.
Betis defender Antonio Amaya headed a high ball back toward his goal, not seeing that goalkeeper Casto Espinosa had charged out of his area. That left Costa alone to collect the ball and roll it into the empty net.
Jorge Molina earned and converted a penalty in the 89th to level for Betis.
Atletico will face Sevilla in the semifinals beginning next week.
Malaga hosts Barcelona later after a 2-2 draw in the first leg.
