Sheffield Wednesday made it back-to-back wins to climb off the bottom of the Championship as substitute Anthony Musaba's injury-time winner stunned Stoke City.
The Dutchman kept his head in a one-on-one with teenage Stoke debutant keeper Tommy Simkin to sentence Alex Neil's Potters to a fourth straight defeat.
But, in a grim encounter, Stoke only had themselves to blame after missing a second-half penalty when Owls keeper Cameron Dawson kept out Ryan Mmaee's spot-kick.
Stoke drop to 20th in the Championship, just two points clear of trouble, having now picked up just two points out of a possible last 18.
