**Dragons started their Rainbow Cup campaign with a 52-32 bonus-point win over Welsh rivals Scarlets.**\n\nWales head coach Wayne Pivac was at Rodney Parade to see a total of 12 tries, seven of which came from the Dragons who were deserved winners. \n\nGlenn Delaney's Scarlets were not at the races and paid the price in a match which had the feel of a pre-season encounter.\n\nDragons took the lead with a neat try from Jonah Holmes. The ball was spread right to Holmes who had Jonathan Davies coming across to cover. Davies should have done better and his missed tackle was crucial.
