**Triple-defending champions Leinster equalled the Championship record of seven five-point victories in succession with a hard-fought 40-5 win over Cardiff Blues at the RDS Arena.** Dave Kearney opened the scoring with less than a minute gone to signal the intentions of Leo Cullen’s men, and Jimmy O’Brien and James Tracy also went over in the first half either side of Aled Summerhill's reply for Blues. Cardiff had further chances in the second period while also producing a determined defensive display, but Scott Penny got the all-important fourth try before he and Michael Silvester added further scores late on. While Leinster celebrate their 15th successive Championship win over Blues, the Welshmen fall to their fourth defeat in five, and remain with just one away win in 2020. # KEY MOMENTS The hosts got off to a flying start with the match’s opening try barely 40 seconds after kick-off, Kearney getting his second score in as many weeks in the corner after smart footwork from Ciaran Frawley. Fly-half Harry Byrne added the extras to signal the worst possible start for John Mulvihill and his men, and Dan Leavy and Peter Dooley made further inroads towards the Blues try-line, before an infringement from Tracy momentarily quelled the danger.
