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.
9. Barry Bannan - 7
Another solid performance from the skipper. Made things happen throughout the game, almost managed to score, and was heavily involved in the opening goal as well. Very decent showing. Photo: Getty Images
10. George Byers - 7
The midfielder had an excellent first half in that combative role, won lots of tackles and was very tidy in position. Not a bad performance - went off with 20 minutes to go and Wednesday behind. Photo: Malcolm Bryce
11. Josh Windass - 7
Had a really bright first half, put himself about excellently and was fantastic for the opening goal. Fizzled out a little bit in the second, but still a good showing. Photo: Steve Ellis
12. Lee Gregory - 6
Came to life in the second half and was one of the best Wednesday players - but was given his marching orders for a second yellow as the Owls were chasing the game. Photo: Steve Ellis
