Stoke were forced to hold off a late Fulham rally to secure a first league win in six games in a topsy-turvy match in snowy conditions at the Britannia.
Some dire defending allowed Stoke to go into the break three goals up, Tuncay kick-starting it with a neat header. Abdoulaye Faye then slid in from close range and Mamady Sidibe half-volleyed the third with the Potters comfortable.
Damien Duff's deflected shot and Clint Dempsey's dipping long-ranger led to a nervy finale, but Stoke just held on.
It was a tense finish to an entertaining match, but home manager Tony Pulis might wonder how his side were forced to hang on in the closing stages having dominated for so long against a lacklustre Fulham outfit.
It was an impassioned display from Stoke, and one that provides a big fillip in their battle to retain top flight status this season.
However, their failure to put Fulham out of sight having dominated the opening hour only allowed the Londoners to produce a late fightback that almost denied the Potters a potentially vital win.
For Roy Hodgson's men, they need look no further than a woeful first-half defensive display when looking for answers as to how they failed to secure an away victory for the ninth straight league match.
