Catalans Dragons shut out Leeds Rhinos for the whole of the second half to secure their first win of the season in Perpignan.
Mick Potter's men found themselves 22-12 down at the interval, but scored 18 unanswered points after that to pick up a surprise victory.
And the points were secured when Aaron Gorrell slotted over a penalty late on, making it 30-22.
Dragons coach Potter was understandably delighted: "It was a well earned victory. We worked very well in the second half and I was very proud of the players but we've still got work to do."
Counterpart Tony Smith was quick to praise the home fans: ""The atmosphere was like a 14th man for the Catalans. We knew it would be tough and were forced into to many errors."
