Ireland kept their quest for successive Guinness Six Nations Grand Slam titles on track by brushing aside spirited Wales with a dominant 31-7 victory in Dublin.
Andy Farrell’s men backed up crushing wins over France and Italy with a third consecutive bonus-point triumph to keep themselves in pole position for further championship glory.
First-half tries from Dan Sheehan and James Lowe paved the way for the reigning champions to equal England’s tournament record of 11 wins in a row.
Wales avoided embarrassment at the Aviva Stadium and briefly threatened an improbable fightback thanks to a second-half spell which brought a penalty try and a yellow card for Tadhg Beirne.
But a first Test try for stand-in Ireland full-back Ciaran Frawley broke their resolve before Beirne atoned for his earlier error by securing the bonus point at the death on an afternoon when flawless fly-half Jack Crowley kicked 11 points.
Ireland’s ominous march towards another clean sweep continues next month against England and Scotland, while winless Wales host France in round four ahead of a possible wooden spoon shoot-out with Italy.
A largely inexperienced Wales team crossed the Irish Sea as overwhelming underdogs on the back of narrow defeats to the Scots and Steve Borthwick’s side.
Visiting head coach Warren Gatland insisted he travelled with belief rather than hope and urged his players to make “everything uncomfortable” for the fancied hosts.
Wales’ bid to disrupt began with some colossal defending as the home team’s early dominance was initially rewarded only by a long-range Crowley penalty.
Yet Ireland’s well-oiled machine persisted with wave after wave of attack to break down the staunch resistance and take control of the scoreboard.
Hooker Sheehan powered over at the end of a line-out maul in the 21st minute to claim his fourth try of the tournament before Calvin Nash later teed up Lowe to touch down in the left corner.
But Sam Costelow’s decision to kick a penalty to the corner failed to pay off, while a couple of costly fumbles ensured they went into half-time scoreless for a third match on the bounce, at 17-0 down.
Any potential fears Wales had of joining Italy in being nilled in Dublin were extinguished within three minutes of the restart as Tomos Williams’ quick tap penalty led to a momentum shift.
Italian referee Andrea Piardi awarded a penalty try at the end of a lengthy review of a collapsed maul on Ireland’s line, with Beirne sent to the sin bin for illegally changing his bind.
Fired-up Wales were well and truly in the ascendancy at that stage but failed to make further inroads on the scoreboard in Beirne’s absence before Ireland restored order.
After the bulldozing Bundee Aki was denied a try on review for Robbie Henshaw’s knock on, Frawley, deputising for the injured Hugo Keenan, gleefully dived under the posts to celebrate his first Test start in style.
Wales came close to a consolation score in the closing minutes, during which Ireland replacement James Ryan was sent to the sin bin.
Yet, with Beirne’s late finish compounding their misery, they ultimately slipped to a 10th defeat from their last 11 Six Nations fixtures as their wait for a first championship win in Dublin since 2012 goes on.
