Sale produced an impressive display at Rodney Parade to claim a bonus-point victory over the Dragons.
HEINEKEN CUP POOL ONE
Dragons 11 (6)
Pens: Warlow 2
Sale 38 (21)
Tries: Hodgson, Cueto, Larrechea, Lobbe, Sevealai'i
Cons: Hodgson 5
The visitors dominated the first half and tries from Charlie Hodgson, Mark Cueto and Daniel Larrechea put them 21-6 ahead at the break.
Gareth Wyatt scored a scintillating solo try after the Dragons attacked from deep to give his side hope.
But Fernandez Lobbe barged his way over and Elvis Sevealai'i wrapped things up with the fifth try in injury time.
The win tightens Sale's grip on Pool One as they now have nine points from the opening two games.
Fly-half Charlie Hodgson stood out for the visitors and scored 18 points in a dominant man-of-the-match display.
The Dragons started well but their good early work was undone when Hodgson charged down Ceri Sweeney's clearance kick and managed to collect the ball for the first try.
The score seemed to rock the Dragons and Sale took control when Robinson's floated pass put Cueto over.
Larrechea added a third try when the Dragons defence reacted slowly to a loose pass and allowed the full-back to stroll in.
The Dragons lost Peter Sidoli and Andrew Hall to the sin-bin in quick succession but despite being down to 13 men, they responded with a superb try for Wyatt from a move that started inside their own 22.
Sale struggled to impose themselves and it was not until the 75th minute, when Lobbe was bundled over, that they could breathe easy.
And the powerful Sevealai'i completed the scoring with a simple score in the closing stages.
Dragons coach Paul Turner:
"I felt we were out-powered at times, and the last two tries that Sale scored were a result of the pounding we took.
"Charlie kicked the ball in the right areas, and while I don't think we were out-classed, we were out-powered.
"That was a little bit of a lesson for us. It was a good big one against a good little one at times tonight, and we were beaten by a far better side."
Sale coach Kingsley Jones:
"Charlie Hodgson is renowned for his passing game, but in the last two weeks he has totally controlled the game for us tactically, and his kicking out of hand must be heartbreaking for the opposition.
"When Charlie is confident there is no-one better as far as I am concerned.
"We are probably in the driving seat now as far as the pool is concerned, and we are delighted to have come here, got the win and collected the bonus point."
