Ireland number ten Sam Prendergast broke the deadlock with a try after 13 minutes, A brilliant Joe McCarthy finish, following a clever Prendergast chip and quick-thinking from Caelan Doris, doubled the lead before Jamie Osborne’s excellent finish after a flowing move made it 19-0 at the break.

"Like I said, sun on the back - the boys had a great start to the game against a very good Quins side, they're very dangerous, so we'll take that."
