Real Betis have won their seventh away match of the season in La Liga with a 2-1 triumph at Real Zaragoza.
Despite decent chances for Helder Postiga and Alvaro Gonzalez, the visitors were ahead at the break when Ruben Castro kept calm to slot the ball past the onrushing Roberto.
Betis continued to soak up pressure from their opponents at the start of the second half and they pounced again before the hour as Jorge Molina fired in following a counter-attack.
Castro could have sealed the victory in the 73rd minute, only to be denied twice by Roberto.
Francisco Montanes pulled a goal back for the hosts soon after with his close-range effort, but they were unable to find an equaliser.
