Wing James Pike, hooker Mark Breeze and number eight Andrew Gwyn bagged tries for the Ospreys in the first half as the home region went into the interval 17-13 to the good - wing Marcus Johnstone and scrum half Robert Lewis crossing for the Dragons, who did their bit to make this another outstanding game.
Ashley Smith kicked a penalty to keep the Dragons in touch, but a try from replacement flanker Ross Cridland midway through the second half gave the Ospreys their first points of the campaign. Gwyn was outstanding for the Ospreys, who used their driving line out to good effect, whilst home centre Jonathan Spratt and Lewis, for the Dragons, were the pick behind.
