Ben Gissing, Shane Horgan and Felipe Contepomi – in for the rested Brian
O’Driscoll – scorched over before the break for the hosts who went on to record their first win in three league outings.
Horgan added his second on the restart – his 10th in 12 competitive games – while Denis Hickie (2) and Niall Ronan were also on target as Declan Kidney’s men chalked up their 15th straight win in Dublin.
David Holwell, who had a flawless nine-from-nine night with his right boot, opened proceedings with a fifth-minute penalty and although Percy Montgomery nullified the 3 point with a kick of his own after 26 minutes it was one way traffic for the rest of the game.
Holwell added a second penalty soon after before Gissing was driven over from close range. Three minutes later Horgan got his first before a Holwell chip through allowed Contemponi to make it 27-3 at the break.
Horgan, Hickie and young flanker Ronan – bagging a cheeky 63rd-minute try, collecting his own chip kick to score – helped Leinster draw within four points of second-placed Munster in the latter stages.
