Adam Byrne scored a hat-trick as Leinster returned to the top of the Guinness PRO12 table with a bonus-point 33-10 victory away at Zebre.
The 22-year-old put his side ahead late in the first half after Zebre made a fast start, before two in the second period wrapped up a comfortable victory – preserving Leinster’s 100 per cent winning record against their hosts.
Centre Tom Daly scored on his Leinster debut after Andries van Schalkwyk put Zebre ahead, before Byrne took over in the second half.
Jack Conan also scored for the visitors, who have won seven of their eight league games so far this season.
Leinster director of rugby Leo Cullen made seven changes following their 24-13 victory against Connacht last weekend, with Daly the headline selection.
Prop Andrew Porter made his first start for the club, while hooker Richardt Strauss made his first appearance of the season.
Zebre were on top as they won the early aerial battle, but handling errors cost them an almost certain try as they coughed up the ball at the Leinster five-metre line.
But when Mike McCarthy was yellow carded, as Leinster were penalised for persistent fouling, they took the lead through Van Schalkwyk, who powered over for the game’s first try.
However, Leinster responded quickly as Daly scored following strong carries from Sean O’Brien and Conan, before Carlo Canna regained Zebre the lead with a penalty.
As the first half progressed, Leinster became more comfortable in possession and it was not long before they moved ahead for the first time courtesy of Byrne after a strong Barry Daly run.
Cullen made three changes in the pack after the break and the extra power immediately paid off after some ferocious work by the forwards created space outside, and Byrne scored his second try from Jamison Gibson-Park’s pass.
Isa Nacewa converted the score from wide on the right, giving Leinster a nine-point lead that they looked unlikely to lose after Canna missed a penalty minutes later.
Shortly after, Conan added the all-important fourth try to confirm a bonus point after Byrne, Noel Reid, Tom Daly and Gibson-Park combined to release the forward to score.
And Byrne wrapped up his hat-trick in style as fly-half Ross Byrne found the winger to dot down after he climbed over full-back Edoardo Padovani to score.
Zebre pushed hard in the final ten minutes to get some points back, but some resolute Leinster defending kept the hosts at bay.
