Sunderland climbed off the bottom of the Championship table after stunning promotion-chasing Derby 4-1 at a rain-lashed Pride Park.
Chris Coleman's team ended a 10-match winless run with first-half goals from George Honeyman and Ashley Fletcher setting them on their way before Matej Vydra replied with his 18th Championship goal of the season.
But Derby never looked like ending their seven-game run without a victory as an Aiden McGeady penalty and a John O'Shea close-range finish boosted Sunderland's chances of avoiding relegation.
