THE Ospreys notched up their second Welsh derby win in a matter of days by beating the Dragons 14-3 at Rodney Parade.
And in doing so, they remain in the RaboDirect Pro 12 title mix.
Eli Walker and Ashley Beck grabbed tries either side of half-time, with fly-half Dan Biggar converting both.
The only points for the Dragons came via a penalty from wing Tom Prydie.
The Ospreys took the lead in the opening minutes.
Full-back Richard Fussell darted down the left and reached the 22 before setting Walker off towards the line and he just managed to ground the ball despite the attentions of opposite number Will Harries.
The home side hit back with a period of pressure of their own and Prydie narrowed the deficit with a penalty.
Biggar missed two difficult penalty attempts, one from wide out and the other from 43 metres.
The Ospreys dominated after the interval and had numerous chances to go further in front.
And they did so when Lewis Robling's kick was charged down near the posts and replacement centre Beck picked up and touched down under the posts, making Biggar's conversion simple.
