Leo Cullen described James Lowe as a "proven finisher" after the New Zealander marked his Leinster debut with two tries in their 36-10 win over Treviso.

Garry Ringrose also scored on his return on a good day at the office for the province, with Cullen happy to get out of Italy with a bonus-point victory that never looked in doubt.

"It was a little bit of a stop-start game," he said.

"The pitch was quite heavy. it was a little bit of a slog. There were plenty of errors from both teams at various stages of the game but we're very happy to get the win.

"They've been in reasonably good form and it's a tricky place to come.

"James is a player we admired from afar. He has credentials as a proven finisher. It was nice for him to get off the mark and to get through 80 minutes. He did a lot of good things during the game. It was good to get him up and running. 

"Garry hasn't played since the summer tour. He's had to do a lot of work to get this point. It was great to see him coming straight back in. He looked at home."

Lowe, who signed from the Chiefs during the summer, scored the first of five Leinster tries in the 16th minute.

Jordi Murphy also crossed the line as the visitors opened up a 17-3 lead at the break, Ross Byrne adding seven points with the boot.

The Italian outfit were first to score after the pause when Juan Ignacio Brex crashed over from close range.

But Ringrose, making his first appearance of the season after shoulder surgery, soon put an end to Treviso’s comeback when he found room to go over out wide before Lowe set up Luke McGrath for the bonus-point try with Brex in the sin-bin. 

There was still time for Lowe to get another as Leinster moved to second place in Conference B.
