World Junior Championship: Ireland Under-20 73 USA Under-20 22Mission accomplished. Andrew Browne’s new-look Ireland team delivered a comprehensive victory, 11 tries, nine conversions for fullback Daniel Green, replete with excellent individual performances and a nice flow at times to their patterns.Corinthians centre Sean David Walsh (Sean David to distinguish him from his team-mate Barnhall secondrow Sean Walsh) crossed for a hat-trick of tries and while a physical handful demonstrated nice balance and footwork as well as lovely light touches from time to time to put others into space.Ireland outhalf Charlie O’Shea excelled, especially in broken play where his stepping ability and pace was unplayable for his American opponents. Three tries was a fitting recompense for that creativity. Garryowen’s Joe Finn had a superb game, so too Alex Lautsou in an excellent backrow where Charlie Keane and Ben Blaney divvied up the workload. Duinn Maguire provided a dynamic presence.Prop Blake McClean featured more prominently than his primary set-piece duties, while right wing Charlie Molony offered a conspicuously positive contribution until his 20-minute red card, an accumulation of two yellow cards.He was unfortunate, not in the first instance, where a failed intercept attempt, merited the sanction but on the second transgression he can feel aggrieved. English referee George Selwood, who otherwise had a fine game, and TMO Francisco Gonzalez came up with two different adjudications for similar infringements.It is incongruous that Molony received a second yellow card, upgraded to the 20-minute red card when American wing Finnian Love jumped into and over the top of him, the Irish player’s eyes always on the ball, and in a separate aerial collision Daniel Ryan who was in the air, gets clattered by the USA’s Jack Firebrace; the latter no chance of winning the contest.Ireland's Daniel Ryan on his way to scoring a try.

The Irish bench added a desired impetus as Daniel Ryan scored an eighth try in eight caps at this age-grade while Jack Deegan completed a clean sweep in the pool as he grabbed tries against England, Argentina and the USA.Replacement scrumhalf Luke Coffey was very tidy on his arrival from the bench, especially in his line-kicking. Ireland scored their first try on 72 seconds through scrumhalf Christopher Barrett, centre Walsh and Green prominent in the build-up.The first of O’Shea’s hat-trick was a classy individual effort. Barrett eased through a gap on the short-side from a scrum, and his halfback buddy dating back to school days at CBC Cork, cruised clear before stepping the fullback, Blake Millar.Walsh got the first of his three tries before he combined with O’Shea, his outhalf looping around his six feet, four-inch frame before racing through a gap and taking a wide arc around the last defender. Three minutes later O’Shea snapped up a loose ball to outpace the cover. Walsh’s second try and another by centre partner Rob Carney saw Ireland lead 45-3 at the interval.The USA were bright in some of their back play living off scraps, Love and centre Leo Keesler-Venables prominent, Firebrace too after his introduction and had a couple of tries chalked off for infringements while Ireland got away with a couple of forward passes for tries without being called back.Seven tries for Ireland before the interval was a strike-rate that was unlikely to be maintained but they did tag on another four, including one for the hard-working loosehead prop Adam Cooper. The influx of replacements, two yellow cards and a red card saw the game lose a little of the cohesion and continuity, but the USA did cross for three; Love, Keesler-Venables and scrumhalf Joseph Sarkees.Ireland appears to have lost a couple of players to injury, Dylan McNeice and Tom Wood, although there has been no clarification yet. Browne’s side will play two crossover matches with opponents to be determined based on the outcome of the final pool matches.Scoring sequence: 1 min: Barrett try, Green conversion, 7-0; 3: O’Shea try, Green conversion, 14-0; 13: Caden penalty, 14-3; 16: Sean Walsh (Corinthians) try, 19-3; 27: O’Shea try, Green conversion, 26-3; 30: O’Shea try, Green conversion, 33-3; 33: Sean Walsh (Corinthians) try, Green conversion, 40-3; 36: Carney try, 45-3.
