Elias Kachunga opened his Wednesday account and Josh Windass made it two in two to guide Wednesday to the third round of the Carabao Cup at the expense of League One Rochdale.
The Owls emerged 2-0 winners at the Crown Oil Arena in a scoreline that flattered the hosts as Wednesday dominated every aspect of the game.
Goals from Kachunga and substitute Windass proved enough, though, and Wednesday face a third round trip to either Fulham or Ipswich.
It was all change for the Owls over the Pennines as Garry Monk switched personnel in every position.
Ciaran Brennan made his debut at centre half amid a completely shuffled Wednesday pack punctuated by academy graduates, with no less than 10 in total.
And after a promising start by Dale, during which Alex Newby warmed the gloves of Joe Wildsmith, the young Owls took a grip on the game.
Adam Reach executed a whipped set piece that brushed the top of the net and was then a whisker away from getting to an Alex Hunt through-ball.
The Wednesday pressure continued and the enterprising Hunt saw a hooked effort cleared off the line by Eoghan O’Connell and Rochdale managed to clear their lines.
Wildsmith remained a spectator as half time approached with the visitors in command but short only of that vital breakthrough.
But that almost came immediately after the resumption when Hunt unleashed a goal-bound drive from distance that keeper Gavin Bazunu expertly palmed wide at full stretch.
Reach slammed past the post via a deflection moments later and the sense was one of a goal on the horizon – which duly arrived on 54 minutes.
Liam Palmer delivered a gem of a cross from the right that Kachunga directed with power past Bazunu.
The Owls were well on top and Palmer fed Reach this time who was again thwarted by the diving Bazunu.
Reach went closer still with 15 minutes to go, crashing a thunderous hit that cannoned off the bar back into play from a counter led by Windass.
Bazuna denied Windass with a fine save that just cleared the woodwork as Wednesday pressed for a second goal to kill the contest.
Börner and Windass spurned chances before the latter finally concluded matters on 86 minutes with an unstoppable shot on the angle from a simple set piece.
Wednesday: Wildsmith, Palmer, Shaw, Brennan (Iorfa 80), Börner, Odubajo, Hunt, Pelupessy (Grant 88), Dele-Bashiru, Reach, Kachunga (Windass 70)
