Stevenage 0-4 Swindon
Swindon Town were in devastating form as dismal Stevenage endured their largest ever Football League defeat.
Raffaele De Vita lashed in a knock down from Matt Ritchie, who then doubled the lead with a shot that eluded Stevenage keeper Steve Arnold.
Arnold was able to save Tommy Miller's penalty after Alan McCormack was brought down by Anthony Grant.
But Miles Storey struck with a header moments later and Adam Rooney finished the rout in the second half.
Swindon boss Paolo Di Canio had previously dismissed this game as less important than Tuesday's League Cup tie against Aston Villa.
But his side looked impressive as they ended a three-game winless run and drew level on points with sixth-placed Notts County in League One.
It was only a second loss out of six for Boro and their first home league defeat since January, but they drop out of the automatic promotion spots down to third.
