Jon Nurse inspired 10-man Stevenage to a terrific win over Accrington.
Within 60 seconds of Michael Warner's 25th-minute sending off Steve Jagielka pounced to put Accrington ahead.
Nurse levelled shortly after the break following good work from George Boyd and he then won a penalty that Dino Maamria converted.
Stevenage extended their lead thanks to a spectacular own goal from Robbie Williams - a moment that summed up Accrington's second-half display.
