GRAND SLAM: Ireland Under-20s complete perfect Six Nations Championship with win in Wales

Six Nations Champions Ireland completed the Grand Slam last night with this win in Wales.

Trailing 10-0 the Irish got back into the game with a try from Jonathan Wren, converted by Ben Healy to take them in 10-7 behind at the interval.

But Ireland came out strongly and a try from Dylan Tierney-Martin, again converted by Healy had them in front for the first time at 14-10.

The Welsh hit back and a converted try nudged them ahead once again.

But replacement scrumhalf Colm Reilly scored a great individual try to give his side a two-point lead with seven minutes to go.

Thomas Clarkson’s converted try with the last play of the game ended all the nerves - and Ireland celebrated a first Grand Slam since 2007.
