Darren Edwards’ side recorded a comprehensive 33-0 win over Mogliano which sees them remain competitive in Pool 3 of the Amlin Challenge Cup.
The Dragons are now five points behind Bayonne in second place though defeats to the French side and pool leaders London Wasps may well come back to haunt the Welsh region.
Despite securing a comfortable win, the Dragons played more than half the game with 14 men after lock Jevon Groves was sent off after half an hour.
It was Tom Prydie who was the catalyst, scoring a try himself and kicking four conversions.
No. 8 Ieuan Jones went over twice as his team ran out easy winners.
Centre Andy Tuilagi touched down first with Jones and wing Will Harries also crossing in the opening period.
Jones added the bonus-point score before Prydie finished off the try-scoring as well as kicking eight points along the way.
