Wednesday booked their place in the play-offs with a sixth successive win, beating Ipswich 1-0 at Portman Road.
Kieran Lee was the man of the moment, stroking home a late second half goal that proved the only goal of the game.
The Owls, knowing that victory was enough to guarantee a top-six slot, started this key contest on the front foot, with Jack Hunt sending a delicious first-minute cross to the back stick where Jordan Spence had to take evasion action and concede a corner.
Adam Reach drilled wide moments later before the hosts made their own statement of intent as Tom Lawrence hit straight at Keiren Westwood and might have done better from close range.
Westwood then punched clear a David McGoldrick curler before the Owls took control of the first half, albeit without troubling Bartosz Bialkowski in the Ipswich goal.
As half time approached it was all Wednesday and they saw penalty claims waved away on 41 minutes when a stray hand from Spence appeared to deflect Glenn Loovens’ shot past the post.
The Owls almost broke the deadlock three minutes into the second half when Ross Wallace fired a trademark long ranger that beat Bialkowski all ends up but crashed against the frame of the bar and back out to safety.
For their part, the Tractor Boys struggled to make any inroads into the Wednesday half as the visitors continued to see most of the ball.
Carlos Carvalhal introduced Fernando Forestieri and Jordan Rhodes midway through the half but it was Lee who finally sealed his side a play-off place on 77 minutes.
Barry Bannan played in Daniel Pudil down the left and the Czech’s low cross was met with a deft Lee flick that sailed across Bialkowski.
Ipswich upped the ante with the clock counting down but there was never any danger of the Owls conceding and they comfortably held out for victory.
Wednesday: Westwood, Hunt, Lees, Loovens, Pudil, Wallace (Forestieri 68), Bannan, Lee, Reach, Hooper (Semedo 78), Fletcher (Rhodes 68)
