Ireland slumped to 24th place as Scots Colin Montgomerie and Marc Warren won the Omega Mission Hills World Cup in sudden death.
Tied 15th starting the final foursomes round, Michael Hoey and Gareth Maybin could only manage a six over par 78 that left them near the back of the field on seven under par.
But they still claimed €47,000 - €23,500 a man - which will help them finance an attack on the Challenge Tour next season.
Scotland claimed World Cup glory for the first time in the event's 53-year history when Montgomerie and Warren beat Americans Heath Slocum and Boo Weekley at the third play-off hole.
It was a sweet win for the Scottish pair, who suffered extra time heartache in Barbados last year when Germany edged them on the first play-off hole.
As Scotland finally joined England, Ireland and Wales as World Cup winners, Monty said: "I didn’t want to say anything to Marc but my play-off record is rubbish.
"But playing with Marc was great and if he is not in the top 20 in the world by this time next year I will be very surprised for he is a fantastic player."
Warren holed a 25 foot par putt on the first play-off hole to keep Scotland's hopes alive and they eventually won with a par four on their third visit to the 18th in sudden death.
Monty added: "Marc holed some crucial putts out there under pressure, none more so than at the first play-off hole to keep us in it.
"After that went in I thought we were favourites to be honest and so it was great to get the job done. After missing out last year, to come here and win is superb."
Scotland set the clubhouse target of 25 under par with a sensational 66 in the final round but were eventually caught by the Americans, who hit a 67.
Warren added: "For this format, Monty is the perfect guy to play with. If you make a mistake, you know he will hit a fine recovery shot to get you back on track and, just like last year, it was an honour to play for Scotland alongside him."
French pair Gregory Havret and Raphael Jacquelin were third on 24 under par after a 67.
But England's Justin Rose and Ian Poulter came up two strokes short of the play-off after making too many errors in a closing 67.
Rose said: "I think we did well to score what we did considering we made some mistakes out there.
"Every time we made a mistake we bounced back brilliantly with a birdie or an eagle but the mistakes proved costly."
South Africa's Retief Goosen and Trevor Immelman combined for a three under par 69 to claim fifth place while Sweden finished tied for sixth along with The Netherlands, Germany and Argentina.
