Wales 23
Ireland 16
WALES produced a passionate performance in Cardiff as Ireland's Grand Slam ambitions were ended.
Following triumphs over Italy, France, and England Ireland were defeated by a powerful Welsh outfit at the Millennium Stadium.
Wales enjoyed a hugely productive first quarter as Ireland were put under significant pressure. As the half wore on Ireland improved ensuring Wales only led 15-9 at the interval.
Four penalties from Leigh Halfpenny in the first 14 minutes had Wales in control early on, but Ireland responded. Johnny Sexton replied with two penalties for the visitors before Dan Biggar landed a drop goal.
Sexton nailed another penalty to keep Joe Schmidt's team in contention, but after the restart Scott Williams skipped clear to score a crucial try for Wales. Ireland were awarded a penalty try which Sexton converted, but Wales stayed cool.
In the closing stages Halfpenny slotted a penalty and Ireland's Grand Slam dream died.
