A goal in each half from Ruben Castro was 0.

Castro's first tally arrived in the 41st minute when he was played in on goal by Jorge Molina and beat goalkeeper Roberto Gago from the center of the penalty area.

The striker doubled his total 20 minutes from time by scoring from 12 yards to put the result out of reach and give Castro nine goals on the season.

Real Betis moves six points clear of the drop zone with the win, while Zaragoza remains rooted to the bottom of the table having lost three of its last four games to sit 11 points from safety.
