Ireland Under-20s remain on course for a second successive Grand Slam after routing Scotland at Scotstoun.

Ireland produced a near perfect performance against a Scotland side that was so far off the pace, and power game of Ireland that it was painful viewing for the Scottish supporters.

Richie Murphy’s side have set up a sold-out decider against England in Cork on March 19, where they will look to make it back-to-back championships for the first time in their history.

Tries by Andrew Osbourne, Fiachna Barrett, Gus McCarthy, Quinn (3), Fintan Gunne, James McNabney, Diarmuid Mangan, Danny Sheahan, Rory Telfer and Oscar Cawley secured the impressive bonus-point win in Scotstoun Stadium.

Ireland made the perfect start as two championship debutantes ran over inside the opening seven minutes as Ireland got off to a perfect start.

With barely two minutes on the clock, a fine kick by Prendergast put Hugh Cooney in.

Quinn then produced a fine side step before finding right winger Osborne, brother of Leinster’s Jamie, who scored on his U-20 debut.

Minutes later, Ireland powered forward again, and after some superb passing moves, Barrett also touched down on his first championship start.

On 15 minutes, Ireland’s lineout worked to perfection as captain McCarthy powered over from close range.

Five minutes later, a fine pass by Barrett found Munster back row Quinn who showed incredible power to charge over to add a fourth try for the visitors and secure the bonus point.

Ireland’s fifth arrived, as Henry McErlean did well to put John Devine clean through, who unselfishly passed across to Gunne to touch down underneath the posts.

Quinn added his second try of the night moments later, as Leinster out-half Prendergast continued his 100 per cent kicking streak.

Ireland then earned a seventh try through McNabney as the defending champions entered the break 47-0 ahead.

The hosts were improved after the restart as Corey Tait charged over from close range, while Luke Townsend, son of Scotland head coach Gregor, kicked the conversion on his U-20 debut.

However moments after coming on, Mangan showed superb strength to run 25 metres and touch down.

Murphy emptied the bench with next weekend’s Musgrave Park decider in mind before Quinn powered over to secure his hat-trick on 65 minutes.

The hosts were reduced to 14 inside the final 10 minutes as second-row Jake Parkinson saw red for a high tackle on Evan O’Connell.
