Getafe have taken complete control of their Copa del Rey tie with Ponferradina by recording a 4-0 win at Estadio El Toralin.
An early goal in each half from Jaime Gavilan, sandwiched either side of a Lafita strike, put the visitors three ahead.
On-loan Valencia forward Francisco Alcacer then notched his first goal for Getafe 21 minutes from time to complete the scoring.
The second leg will take place at Estadio Coliseum Alfonso Perez on November 28.
