The Owls were more compact and provided more solidity than in recent outings but offered little going forward but for a couple of first-half half-chances.
These are very, very worrying times for the Owls, who after 11 competitive matches this season are still searching for a win under their new manager and are rock bottom of the Championship.
Their defeat in the Midlands saw Wednesday go more direct and saw the return of a handful of faces that haven’t features a great deal in recent weeks.
There were once again loud chants of protest against the club’s owner and chairman as the fans provided plenty of noise from the away end.
Here are our player ratings from the Owls’ latest disappointment.
9. Anthony Musaba - 4
Was switched with Delgado having been given whiplash by West Brom’s right side. Simply couldn’t get into the game or offer that little bit of something in tight spaces. | UGC / Steve Ellis
10. Ashley Fletcher - 5
Pounced on an early gift from WBA to put a cross in for Delgado, who couldn’t lunge far enough. Took on a shot that was blocked. Struggled for much joy, as have all Wednesday strikers this season. | UGC / Steve Ellis
11. Michael Smith - 5
Belted about and offered work rate. Made a good aerial impact and once or twice held it up nicely on a few occasions but his impact faded. | UGC / Getty Images
12. Pol Valentin - 4
On for Delgado on 58 minutes. Couldn’t offer any impact. His shot at the death summed things up. | Ellis / UGC
