Cape Town - Ireland proved far too strong for their Six Nations rivals Scotland in their Pool A Rugby World Cup clash in Yokohama on Sunday.
As it happened | Ireland v Scotland
Ireland won 27-3 after leading 19-3 at half-time.
With their bonus-point victory - barring an upset of epic proportions - the Irish all-but set up a mouth-watering quarter-final clash against the Springboks on Sunday, October 20 in Tokyo.
With Ireland likely winners of their pool - and the Springboks destined for the runner-up spot in their pool following their 23-13 defeat to New Zealand on Saturday - the two sides will lock horns in the playoffs.
Ireland, the world's No 1 side heading into the tournament, scored four tries through lock James Ryan, hooker Rory Best, prop Tadhg Furlong and wing Andrew Conway.
Flyhalf Jonathan Sexton and scrumhalf Conor Murray each added a conversion, while replacement pivot Jack Carty contributed a penalty.
Scotland replied with a solitary penalty by scrumhalf Greig Laidlaw and now face an uphill battle in order to qualify for the playoffs.
Ireland picked up a full-house of five points for their victory to top Pool A, while Scotland left empty-handed.
Ireland's next assignment is against hosts Japan on Saturday, September 28 (09:15 SA time), while Scotland face Samoa in their second fixture on Monday, September 30 (12:15 SA time).
