Nations Championship - Ireland 42-12 Argentina: Hugo Keenan scores hat-trick in statement victory for Andy Farrell's charges in Dublin

Hugo Keenan scored a hat-trick as Ireland notched six tries in a big Nations Championship bonus-point win over Argentina

Hugo Keenan notched a hat-trick as Ireland blew Argentina away in Dublin to secure a statement 42-12 Nations Championship victory.

On a night of big positives for Andy Farrell's charges, they scored six tries through full-back Keenan's three, hooker Dan Sheehan, fly-half Sam Prendergast and replacement front row Ronan Kelleher.

Argentina scored two tries through wing Mateo Carreras, and actually landed the opener in the Test, but by 55 minutes the contest was over, with the visitors totally outplayed.

Indiscipline also proved a thorn for the Pumas again as centre Justo Piccardo and replacement lock Efraín Elias were shown costly yellow cards, with a vibrant Ireland needing little invitation to attack and score points.

A typically cagey and physical beginning to the fixture saw the visitors strike for the opening try in the 10th minute - wing Carreras claiming an inch-perfect Tomás Albornoz kick-pass over the head of final defender Craig Casey in a wonderful piece of playmaking skill.

The Irish response came within five minutes, though, as a Casey-led counter-ruck earned territory, before a scintillating backline move saw Robert Baloucoune arc round and make great yards at pace, Mack Hansen offload inside brilliantly, and Keenan collect to finish.

Prendergast added the conversion for an early lead after Albornoz had earlier failed off the tee, while three superb Irish turnovers soon earned them the chance to strike again.

First, flanker Nick Timoney exquisitely won a breakdown penalty by his own try-line to quell a Pumas surge. Then, Tadhg Beirne got up to steal an Argentina lineout, while Timoney came up with the breakdown goods again soon after - this time on the halfway line.

When Ireland kicked to touch and into 22, an intricate move off a lineout saw Sheehan play a blind inside ball for Timoney to charge forward. The Ulster flanker was stopped just short, but quick Casey service saw Sheehan fly over for a 14-5 lead.

Five minutes later, Ireland had their third try through Keenan again. Ryan Baird won another lineout steal to instigate the attack, with Ireland's full-back then doing marvellously well to battle and bounce his way over past a number of Argentina defenders.

When Prendergast converted, the Irish lead stood at 21-5, and worse looked likely to follow when Pumas centre Piccardo was sin-binned for giving away a cynical penalty in not being back 10 metres off a Sheehan quick-tap penalty.

Ireland failed to add a fourth score before the break, however, as Sheehan was illegally halted in the corner by replacement Leonel Oviedo - referee Luke Pearce just about decreeing penalty-only was sufficient.

Ireland put it behind them to score their bonus-point clinching fourth try less than two minutes into the second half, with Prendergast throwing a dummy bought by Marcos Kremer and racing in from deep.

The Pumas replied with their second try four minutes later, when centre Santiago Chocobares made the key break and Carreras powered his way over past Keenan, but Ireland then kicked on to another level.

The tireless Beirne won a trademark breakdown penalty deep in the Argentina half to earn the platform, with quick hands from Tadhg Furlong, Joe McCarthy and then Baird giving Keenan the space to dive over for his third.

With Baird continuing to cause havoc at the Argentina lineout with steals, the Pumas were soon back down to 14 players when the TMO showed images of Elias catching Keenan high in a shoulder-to-head tackle.

From the very next lineout, Ireland constructed a tight maul which drove forward at pace and was finished by Kelleher for their sixth try of the night.

Replacement Ciaran Frawley's conversion brought Ireland to their eventual 42-12 score, and head coach Farrell will be irked somewhat they failed to add more points from what was left in the Test.

Hansen showed some sensational skill and came close to both creating and scoring tries in what remained, but Kelleher's lineout performance was the central reason behind the home side failing to score more tries - the replacement coughing up a host of possession at the set-piece.

What's next?

For Ireland, they next face Fiji in their second Nations Championship Test of the autumn at the Aviva Stadium in Dublin on Saturday, November 14 (8.10pm kick-off).
