Wing Tonderai Chavhanga scored only the third-ever hat-trick of tries for Newport Gwent Dragons but it was not enough to prevent his side's second LV= Cup defeat this season against Northampton, who ran out 30-20 winners.
Stand-off Ryan Lamb booted 20 points as the Saints turned on the style after the interval to overturn a 10-6 half-time deficit.
Flanker Phil Dowson and wing Jamie Elliott got the visitors' tries. Tom Prydie added a penalty and a conversion in vain for the home side.
