2-0 Diego Costa 63'
Getafe simply didn't show up and duly paid the price - with both eleven and ten men...
... Rayo took their chances in a game that they dominated ...
Getafe may have held the giants of Real Madrid to a single goal last week, but this time around the comparative minnows of Rayo managed double that tally in far easier circumstances as the visitors found themselves completely overwhelmed in Vallecas.
The hosts were by far the better side in the first half and perhaps should have had an advantage ten minutes in when Miguel Moyà appeared to fell Piti in the box, but referee Álvarez Izquierdo saw nothing.
Rayo deservedly took the lead ten minutes before the break when Michu was left unmarked in the box to fire a rebounded effort past Moyà after a cross from José Casado. There were suspicions of offside but nonetheless the goal had been coming.
Geta's chances of a fightback were all but extinguished on the hour mark when Míchel was issued a straight red card for what Izquierdo interpreted as a foul preventing clear goalscoring opportunity for Diego Costa - a dubious decision.
And it fell to Diego Costa himself to completely end the game just three minutes later with a neat header from a cross by José Maria Movilla.
Thus Rayo leapfrog Getafe in the standings, going a point ahead of the south side outfit who remain on 27 points.
Next week the second half of Getafe's season begins with the visit of Espanyol to the Coliseum.
