A trip to promotion-chasing and in-form Norwich always looked a tough task for the Owls and so it proved on Easter Monday at Carrow Road.
A brace from Bradley Johnson in a scintilating first half did the damage as the Canaries strengthened their elevation credentials.
And it was no more than Norwich deserved, taking a grip on the game from the first whistle.
Wednesday did create chances themselves but few compared to a home side showing the right form at the most important stage of the season.
A frantic opening was bossed by the Canaries and only some stout defending kept them at bay.
Filipe Melo, making his first start for the Owls, threw himself in front of a Stephen Whittaker drive and Norwich had a penalty appeal turned down moments later when Claude Dielna tangled with Cameron Jerome.
Alexander Tettey forced Keiren Westwood into a diving save, Tettey smashed another effort narrowly off target, before the Owls countered and carved two chances in as many minutes.
First, Lloyd Isgrove burst down the right and shot across John Ruddy but wide, then Caolan Lavery had a clear sight on goal eight yards out from a Chris Maguire cross but headed over.
Norwich promptly resumed control and Whittaker went close following a neat four-man move on the half-hour.
And on 34 minutes, the hosts took the lead. More pressure saw a deep cross from the right land right on the head of Johnson, who directed a well-placed effort beyond Westwood into the far corner.
It was one-way traffic to the break and just as it seemed the Owls would hold out and have the time to re-group, Norwich doubled their lead.
Dorrans sent a corner straight into the heart of the danger zone and Johnson drilled past a clutch of players inside the six-yard box to make it two.
Stuart Gray shuffled his pack at half time, sending on Atdhe Nuhiu to lead the line, while Lewis Buxton replaced Marnick Vermijl.
And they did start the second period brightly but Norwich played with the full comfort of that two-goal cushion.
Indeed, Alex Neil’s side barely laid a glove on Wednesday throughout the second 45 but had enough of the ball to prevent any kind of comeback from their opponents.
This win took the Canaries into the automatic promotion equation and based on the quality of a first half performance that simply overpowered the visitors, few would argue against them staying there.
