Leinster battle past stubborn Cardiff to seal bonus-point win

United Rugby Championship leaders Leinster overcame fierce Cardiff resistance to claim a 33-20 bonus-point victory at the Arms Park.

Leinster, unbeaten in the competition against Welsh opposition since Cardiff beat them more than two years ago, conceded 15 unanswered points and trailed just after half-time.

But they ultimately overpowered their hosts to post a ninth win of the URC campaign as tries from wing Rob Russell, number eight Max Deegan, hooker John McKee and replacement prop Michael Milne's double saw them home, while fly-half Ross Byrne kicked four conversions.

Cardiff, inspired by two tries from Wales international prop Rhys Carre and an Aled Summerhill touchdown, pushed their opponents hard, yet their only other points came via a Tinus de Beer conversion and penalty.

Leinster blasted out of the blocks and rocked Cardiff with two tries inside the first 10 minutes.

Prop Tom Clarkson proved key in the opener, breaking clear before finding Russell with a scoring pass, then Deegan crashed over from close range and one Byrne conversion made it 12-0.

Cardiff were rocked back on their heels, but they put some promising passages of play together either side of a De Beer penalty, with Summerhill and Owen Lane offering attacking threats.

Cardiff continued to make headway and they were rewarded four minutes before half-time through a lineout move straight off the training ground that worked to perfection.

Carre was the beneficiary, finishing powerfully after scrum-half Ellis Bevan put him in space from accurate set-piece possession, then Carre struck again on the stroke of half-time after De Beer’s conversion cut Cardiff’s deficit to two points.
