The Blues put the wind up Leinster on their own patch and were unlucky not to leave the RDS with at least a losing bonus point after a magnificent second half fight back.
When they were trailing 20-6 at half-time there seemed no possibility of Dai Young’s side returning to Wales with anything other than a bloody nose.
Yet within 20 minutes of the re-start they had not only got on level terms, but then edged ahead. It was a remarkable turn-around than stung Leinster into a strong rearguard action that eventually saw them deliver to new coach Joe Schmidt his first competitive win 34-23.
Leinster threatened to blow the Blues away with their fast start, which saw them notch 14 points in 10 minutes. Shane Jennings surged over the line for a try within four minutes and then Isa Nacewa followed suit five minutes later
The power of the home pack put the Blues pack to the sword in the early exchanges and just before the break Young had to bring on experienced prop Tau Filise in place of Tom Davies to shore up his front row.
Davies, making his first Magners League start after his summer transfer from Doncaster Knights, was penalised five times for collapsing the scrum and without a solid platform the Blues simply couldn’t function.
Leinster took full advantage of their dominance and as well as those two tries, both of which Nacewa converted, they also turned the screw with two penalties from their Fijian winger to build that 14 point interval lead.
But the Blues hit back with tries from Bradley Davies and Richie Rees and Parks’ boot pushed them into a three point lead on the hour.
As the 16,000 home crowd got more and more restless, so Leinster went back to basics up front and finally generated enough forward power to create chances for Fergus McFadden and Ian Madigan to cross.
Those tries not only delivered victory, but also clinched a bonus point and denied the Blues anything.
