A 3-0 win over Oldham on Easter Monday saw the Owls move back into second spot in League 1.
Goals from Gary Madine, Miguel Llera and Ryan Lowe settled the contest as Wednesday posted their seventh win from Dave Jones' eight games at the Hillsborough helm.
Madine's opener came just before the interval, with Llera adding a second on 67 minutes, glancing home from Keith Treacy's centre.
Lowe then made sure of the points scoring with his first touch after coming off the bench with ten minutes left on the clock.
Fresh from Saturday's derby triumph over Huddersfield, Wednesday made a lively start against the Latics.
Michail Antonio breezed past his marker inside the opening two minutes, demonstrating electric pace, but his dangerous cross was well cleared by Reece Brown six yards from goal.
But Oldham - who began the day six points from the League 1 drop zone - might have felt unfortunate not to have broken the deadlock with the very next attack.
Nile Ranger's clearance from an Oldham flag kick sat up nicely for skipper Dean Furman, who made good connection from 20 yards with a volley that flew just wide.
Antonio then showed superb awareness to intercept a loose ball in midfield before racing goalwards but Oldham keeper Dean Bouzanis saved well in the one-on-one situation.
As the half time whistle approached, it was a relatively even affair with the Owls perhaps edging the contest in terms of chances, as Chris Lines' curled effort finished just past the post on 40 minutes.
Robbie Simpson saw his flicked strike trickle just wide of Stephen Bywater's goal before Wednesday got their noses in front after 43 minutes.
Miguel Llera won possession in the Owls' half before charging upfield and delivering a pinpoint accurate cross for Madine to nod past Bouzanis.
In search of an early equaliser after the resumption, Oldham made a good start as ex-Owl Shefki Kuqi tested Bywater with a low strike from an acute angle on the break.
Second half substitute Treacy was out to make an immediate impact on the game as the on-loan Burnley man fired just wide after his introduction from the bench.
Bu the midfielder made his mark moments later, delivering a perfect free kick from the right which Llera glanced into the back of the net to make it 2-0 to the Owls.
With the margin extended to two goals, Wednesday began to look likely to increase their advantage further as Treacy struck wide following great wing play by Antonio.
The game was put beyond doubt on 80 minutes when Lowe, with his first touch after coming on off the bench, nodded home Treacy's centre to wrap up a good day at the office for Wednesday.
