Sheffield Wednesday's lacklustre start to the season continued as they were dumped out of the Carling Cup at home by rampant League Two side Wrexham.
Mark Jones capped a fine display with Wrexham's final goal
The Championship hosts were two down by half-time, Neil Roberts converting Mark Jones' knock-down and Chris Llewellyn dispossessing Tommy Spurr to score.
Matty Done added a third, bundling home Jones' cross, before Glenn Whelan's screamer gave the Owls some hope.
But Jones finished things for Wrexham, cutting inside to curl home a beauty.
