Malaga moved above Betis into fourth spot - for at least 24 hours - as goals from Joaquin, Javier Saviola, Ignacio Camacho and Roque Santa Cruz saw them thrash Granada 4-0 at La Rosaleda.
Elsewhere, Ernesto Valverde's first Primera Division match in charge of Valencia ended in a 1-0 win at Osasuna, Roberto Soldado netting the game's only goal 11 minutes into the second half in Pamplona.
The win was Los Che's first on the road in La Liga this term, Mauricio Pellegrino having paid the price for the poor form when he was sacked earlier in the week after the club picked up only two points from their first seven away games.
Carlos Martinez's stoppage-time header salvaged a 1-1 draw for Real Sociedad as they stretched their unbeaten run to five league games with a point against Getafe at Anoeta.
The game suddenly came to life in the final few minutes when Angel Lafita nodded home from Jaime Gavilan's cross on 87 minutes, but Sociedad responded immediately as Martinez rose highest at the far post to convert Alberto de la Bella's cross.
