Chesterfield youth team suffered their first pre-season defeat as they lost 2-0 to a resilient Sheffield Wednesday side.
Two goals in two minutes from striker Roy Rudonja in extra time was the only difference between the two sides in what was a very close encounter.
The Spireites made only one change to the starting XI that drew with 0-0 with Wednesday just five days previous, with a trialist starting in place of midfielder Oliver Brock.
Boss Dave Bentley was also given more options to choose from as striker Joe Mathers was back in the squad after recovering from an illness.
Chesterfield started the game on the back foot, and nearly went a goal down instantly after a shot from Owls midfielder Ayo Oblieye was smartly saved by ‘keeper Cameron Mason.
The visitors went close again just moments later when Nick Haugue’s 25 yard effort went narrowly wide of the post.
The home side then started to find their feet and had there own chance to take the lead when Joshua Scully’s corner found striker Bradley Bowland unmarked, unfortunately his acrobatic effort cleared the bar.
Chesterfield continued to press from then on and let some chances go begging, just before the half hour mark attacking midfielder Mark Fereday was sent through one on one after a pin point pass by Scully, however his effort was well saved and the rebounding effort was hit wide.
Scully was unlucky not to have his name on the score sheet just before halftime, when he saw his 25 yard free kick come rattling back off the cross bar and out for a goal kick.
Both sides then made changes at half time, with Chesterfield bringing on Defender Jamie McNicholas for Thomas Colton and attacking players Brock and Mathews in place of Fereday and Ben Partridge.
Chances were few and far between during the second half, a strong midfield battle with hard challenges and heavy amount of possession dominated most of the play, the closest that anyone came to scoring was Wednesday right back Elias Moses, whose 25 yard free kick was saved well by Mason.
However as time went on the cracks in the Chesterfield team began to show, something Sheffield Wednesday started to exploit, and as the pressure started to build, the Spireites were forced into playing sloppy passes and route one play, something the visitors dealt with easily.
With this the Owls nearly took a lead with 15 minutes remaining when after some good passing between the midfield it opened up space for a great pass to substitute Charlie Dawes whose low drive with whistling past the post.
Chesterfield thought they nearly won it with just 5 minutes left, when a flick on found its way through the defence to Mathers whose shot was well saved by the out rushing Jow Wildsmith.
The Owls continued their heavy onslaught and their patience finally paid off in the 90th minute when a driven cross by Moses was flicked on near post by Emmanuel Dieseruvwe to fellow forward Rudonja who headed in from a yard out.
It only took 30 seconds for the Owls to double their lead, when a good through ball found Rudonja in space and his neat finish beat Mason.
Speaking after the game, manager Dave Bentley believes his side should have held on, despite playing poorly.
He said: “Sometimes you don’t play well and when its nil-nil, that’s the time you’ve got to see it through.
“I thought we fell asleep at one or two moments, it’s just something we have got to go out and work on.”
Bentley will be hoping his side will improve come the next friendly, on Friday 20th July away at Hucknall.
Chesterfield line up: Mason, Slack, Broadhead, Whittaker, Colton, Hewitt, Scully, Trialist, Partridge, Fereday, Bowland. Subs: McNicholas, Brock, Mathers.
