AUSTRALIA'S Jason Day rode an emotional wave of crowd support to win the World Cup of Golf by two strokes at Royal Melbourne after an enthralling duel with Danish runner-up Thomas Bjorn.
World number 18 Day, mourning the loss of eight relatives killed in the Philippines by Typhoon Haiyan, broke clear of the tenacious Bjorn on the par-four 16th with a nerveless clutch putt for par before holding firm in the final holes. Day's final round of 70 left him with a 10-under total of 274 in the $8 million biennial tournament where players have competed for individual honours after previously being solely a team event.
Collecting a $1.2 million winner's cheque, Day will also share $600,000 with world number two compatriot Adam Scott after the pair combined to drive their home nation to a runaway 10-stroke win over the US in the team component.
Ireland shared 11th with Sweden on nine-over. Graeme McDowell slumped into a five-way tie for 15th (worth $100,000) on one-over after a closing 75. Shane Lowry finished seven shots behind his team-mate in 44th place ($35,500) after birdie-free final round 74.
