Dan Sheehan stars for Leinster in win over Dragons
Leinster came away from Rodney Parade with a bonus-point victory as Dragons fell to their third home defeat of the season.
The opening two home fixtures for Dragons saw them lose to Edinburgh and Cardiff and this latest defeat crowned a miserable weekend for the Welsh regions, with all four of them losing at home.
Dan Sheehan, Thomas Clarkson, Ciaran Frawley, Charlie Ngatai and Scott Penny scored Leinster's tries with Ross Byrne converting four.
Aneurin Owen scored Dragons' try with Cai Evans kicking a penalty and a conversion.
Dan Sheehan gets his first Leinster try sine returning from World Cup duty. Ross Byrnes adds the etras.
