Ireland U20s v Wales U20s Dubarry Park, Friday 7.35, Live RTé 2
The best Ireland U20 Six Nations performance since the competition was established in the season 2005-2006 rocketed Allen Clarke's side to the top of the table on points difference from England and Wales.
Better again, Ireland have a considerable points advantage. France and Scotland are one point behind the leading three.
The basic fact is that Ireland have the destiny of the title in their own hands and a more than handy bunch of players to get the job done with a certain Rhys Ruddock as their captain.
The son of former Wales Grand Slam coach Mike Ruddock is a quality individual, by all accounts.
The heavily outweighed front five have scrummaged well. The handicap of size should be partly addressed by the first start for 130kg prop Stewart Maguire.
The half-back combination of John Cooney and James McKinney has not functioned as well as it can do. There is more to come from them, especially opposite the exquisite playmaking skills of Wales out-half Matthew Jarvis and the try-scoring creden-tials of winger Kristian Phillips.
Ireland: A Conway; D Hudson, B Macken, N Spence, T O'Halloran; J McKinney, J Cooney; J O'Connell, N Annett, S Maguire, D O'Callaghan, B Marshall, R Ruddock (capt), D Ryan, P Butler.
Wales U20: D Fish; J Loxton, B John, S Williams, K Phillips; M Jarvis, G Davies; D Watchurst, R Williams, S Gardiner, S Macauley, L Peers, M Allen, J Navidi (capt), T Faletau.
