Nabil El Zhar, Jonathan Viera, Pedro Bigas and Mubarak Wakaso were on target for Las Palmas to ensure a miserable outing for Espanyol.
Las Palmas romped to a 4-0 win over Espanyol in La Liga to ensure its visitor's lingering relegation fears remain.
Espanyol was hit by the early injury loss of midfielder Abraham but Las Palmas had to wait until first-half stoppage time to unpick the visitor.
Jonathan Viera slid a pass through for Nabil El Zhar to steer a shot through goalkeeper Giedrius Arlauskis.
Viera got in on the act himself by drilling into the bottom corner four minutes after the restart and his cross was headed home by Pedro Bigas in the 56th-minute to complete an emphatic period for Quique Setien's side.
