It was an eventful afternoon at Hillsborough as the Owls drew 3-3 in their first game of the 2022/23 season, but while Fisayo Dele-Bashiru shone and twice came to the rescue, there was still plenty of cause for concern.
The Owls took the lead when Barry Bannan played in Josh Windass whose ball across goal was knocked in by Marvin Johnson.
However, Pompey were level when Connor Ogilvie latched onto some slack defending to head in from Marlon Pack’s cross.
Dele-Bashiru scored the first of his double on 53 minutes with a superbly struck shot to put the Owls back into the lead but the visitors were back in it again four minutes later through Michael Jacobs’ close range goal.
Pompey then went in front when Colby Bishop took advantage of yet more sloppy defending to head in Joe Pigott's cross but Dele-Bashiru came to the rescue again with nine minutes of normal time remaining whith another excellent drive.
Wednesday striker Lee Gregory was sent off in the final few minutes to cap off a dramatic opener at Hillsborough.
Here are our ratings from another mad afternoon in S6.
5. Ben Heneghan - 5
Like the others, Heneghan did ok in the first, but the back three were unable to deal with crosses into the box far too many times - and were punished for it. Photo: Malcolm Bryce
6. Michael Ihiekwe - 5
Showed some good passing ability in the opening 45, however - like his defensive teammates - was left wanting in the second 45 as the backline was punished on three occasions. Photo: SWFC
7. Marvin Johnson - 6
A very mixed performance from Johnson, who was very good going forward and took his goal well, but will be disappointed with the goals that came from his side. Photo: Malcolm Bryce
8. Fisayo Dele-Bashiru - 8
Wednesday's star man in the heart of the midfield... Two rockets pulled them out of the mire when they were up against it. Took his goals brilliantly, and his overall play was good as well. Photo: Malcolm Bryce
