Leinster rally to claim Cardiff win
Leinster scored two tries in the final 10 minutes to snatch a battling 34-23 victory over the Cardiff Blues in a lively Magners League encounter at the RDS.
Joe Schmidt's side went about securing the bonus point in a roundabout way, with Fergus McFadden and Ian Madigan crossing in the closing stages after early efforts from Shane Jennings and Isa Nacewa had them 14-0 ahead.
Cardiff rallied impressively in the third quarter, grabbing tries through Bradley Davies and Richie Rees, and a penalty from Dan Parks edged the Welsh region in front at 23-20.
But McFadden's try helped Leinster reassume control and it was fitting that young out-half Madigan scurried over for the clinching score.
Jonathan Sexton missed out on his first appearance of the season for Leinster when injuring himself in the warm-up, so academy player Madigan stepped in at number 10 for only his second start for the province.
Cardiff travelled on the back of an encouraging bonus-point victory over Edinburgh last weekend, and gave competitive debuts to prop Tom Davies and New Zealand flanker Michael Paterson.
