Wednesday and Watford shared the points in a Hillsborough stalemate.
Both sides hit the woodwork but neither could find a way through but for the Owls, a vital point goes on the Championship board.
It could have been all three based on the possession stats as Danny Röhl’s men bossed large periods of the game.
The Hornets arrived in S6 four points shy of the play-offs but it was Wednesday who opened the contest on the front foot.
With Barry Bannan pulling the strings, the Owls took command and the skipper forced a superb diving save from Ben Hamer on the 15-minute mark.
Moments later came a clash of legs in the box between Anthony Musaba and Jamal Lewis but the referee waved away the hosts’ penalty appeals.
Wednesday continued to press, then Watford broke, won a free-kick 25 yards out, and Mattheus Martins’ hit took a wicked deflection off the wall before hitting the post.
The Owls had a let-off from the visitors’ next attack as Vakoun Bato motored through on goal and slipped in Martins on the angle but the forward fluffed his lines with the empty net gaping.
Wednesday assumed control with half time looming and were within a lick of paint of heading down the tunnel in front.
Iké Ugbo took a short feed from Josh Windass into his stride, turned his marker, and fired a whistling drive that crashed against the inside of the upright.
Musaba’s header from the rebound was gratefully gathered by Hamer.
The story of the second half was much the same, with Wednesday seeing more of the ball and Watford playing on the counter.
There seemed little prospect of a breakthrough at either end until the 70th minute when Wednesday went mightily close to breaking the deadlock.
Bannan swung a delicious set piece to the back stick, where Hamer denied the onrushing Di’Shon Bernard. The ball, though, squirmed away from the keeper, who rescued his side right at the last on his line.
The closing stages saw the Owls pour numbers forward in pursuit of a winner and it so nearly came with a minute to go.
Musaba expertly weaved across field and from all of 25 yards unleashed a bullet of a shot destined for the top corner, only for Hamer to somehow stretch every sinew and tip athletically over the bar.
Wednesday: Beadle, Valentin, Bernard, Famewo, Johnson, Bannan (M Diaby 86), Palmer, Gassama (Wilks 90), Musaba, Windass (Smith 46), Ugbo (Cadamarteri 71)
