Wolves were unable to prevent their winless run extending to six Premier League matches as they lost 2-1 at Cardiff City thanks to Junior Hoilett's stunning late strike.
Nuno Espirito Santo has come under pressure of late because of Wolves' poor run and they put in another disappointing showing in Wales on Friday, as Cardiff clawed their way out of the bottom three.
Wolves were second best for most of the first half, but went into the break ahead thanks to Matt Doherty's second Premier League goal.
Cardiff stepped things up after the interval and deservedly levelled in the 65th minute through Aron Gunnarsson, and Hoilett netted a glorious winner 13 minutes from the end to consign Wolves to a fifth defeat in six games.
