Joey Carbery enjoyed a full debut to remember as he scored two tries for Leinster in their opening 20-8 Guinness PRO12 victory over Treviso.

The 20-year-old was given his first start at fly-half by Leo Cullen and it paid off with two tries in the first half as Leinster flew out of the blocks.

But they were pushed hard by a Treviso side who kept battling, and thanks to Marco Fuser’s try late in the first half, continued to dream of a first win in Dublin.

But in the end, Leinster had a little too much, and replacement hooker James Tracy’s try wrapped up the win.

Carbery was highly-touted as a youngster coming through, and after making his debut off the bench last season, he made the perfect start on his first start.

With just three minutes gone, Leinster set up camp on the Treviso line, and when the ball was spread, Carbery showed his quick feet to dance out of a couple of tackles and then go under the posts. Fergus McFadden converted to make it 7-0 early on.

Treviso should have cut the deficit with a penalty in front from the 22 but Tommaso Allan’s effort clipped the post and away.

And as one fly-half struggled, his opposite number showed all his talent with a second, magnificent try.

Carbery had already shown his quick feet, but he clearly has pace too, and after breaking through he raced away, beat the last man and sprinted over on the left for the second Irish try of the evening.

McFadden was off-target with the conversion, but when he knocked over a penalty just after the half-hour, Leinster looked to be in control at 15-0.

However just before half-time, Treviso struck, and it was a lovely try. Having got themselves into the Leinster 22, scrum-half Giorgio Bronzini produced a lovely dummy and inside pass for Fuser and he burst through before reaching over for the try.

In the second half Treviso fought hard, and got back to within a score when Allan knocked over his first kick of the evening with a penalty.

Then on the hour there was a momentous occasion as Treviso brought on fly-half Ian McKinley, who had come through the ranks in Dublin before an eye injury looked to have ended his career.

After a long road he is a part of the Treviso squad this season and got his chance against his former team to try to orchestrate the victory.

Leinster had more of the ball though, and they finally got the try that made the result safe, from a huge rolling maul. A lineout on the 22 was cleanly taken and the Leinster pack marched inexorably towards the line, with Tracy the man to emerge.

Leinster gave it everything for the fourth try but couldn’t manage it, having to settle for four points from their first game of the campaign.
