MELBOURNE - Jason Day plans a few celebratory drinks after winning the $8 million World Cup of Golf on home soil on Sunday before turning his efforts to raising awareness for the devastated Philippines where eight of his relatives were killed by Typhoon Haiyan.
The grieving 26-year-old competed with a heavy heart at Royal Melbourne but played some of the finest golf of his life to seal the individual trophy by two strokes and drive Australia to a runaway victory in the team component.
Day's triumph was watched by his Filipino-born mother Dening, whose own mother was lost in the typhoon, and the pair shared an emotional embrace by the 18th green after the final par-putt rolled in front of a roaring gallery.
Matt Kuchar shot 71 to finish fourth in individual stroke-play, three behind Day.
Ryo Ishikawa (69) of Japan and Thailand's Kiradech Aphibarnrat, who shot 70, finished tied for fifth, seven behind the winner.
David Hearn of Brantford, Ont., fired his third straight round of 71 to finish in a tie for eighth. Ottawa's Brad Fritsch shot 73 to finish in a tie for 25th.
Prior to the tournament, Day said he had hoped his team mate, world number two Adam Scott, would carry him through, but he ended up shouldering the load after the Masters champion opened with a four-over 75 including a nightmare quintuple bogey on the 12th.
Locked in a two-way battle with seasoned Dane Thomas Bjorn in the back nine, Day drained a seven-foot putt for a crucial par on the 16th to take a one-stroke lead and held on to celebrate an emotional victory.
"It feels great, I just really don't know what to think right now," the world number 18 told reporters after notching just his second PGA Tour win, three years after his maiden title at the Byron Nelson Championship.
"Today I learnt a lot about myself ... I am definitely going to embrace being a World Cup winner tonight and I won't go too crazy but I will definitely have a drink or two and, you know, right now I am just the happiest guy."
Day won $1.2 million for sealing individual honours at the biennial tournament, and will share another $600,000 with Scott for winning the team trophy, 10 strokes better than the American duo of Kuchar and Kevin Streelman.
Denmark and Japan finished tied for third at 5-under in the team event. Canada finished fifth at 2-over.
"Right now we're in the process of doing something," Day said when asked about relief efforts in the Philippines.
"Definitely, we'll probably most likely set something up and definitely be giving some money or raising money and trying to raise awareness to what has really happened over there.
"The devastation and the tragedy that's gone on over in the Philippines is very difficult for us to see because we're living in such a great country.
"Once you know of someone or are related to someone who has gone through something like that it's very close to the heart."
Day and Scott's triumph in the team event was Australia's fifth but first since Peter Fowler and Wayne Grady won in 1989.
Australian golfing luminary Peter Thomson, a five-times British Open winner who clinched the 1954 and 1959 trophies with compatriot Kel Nagle, was at Royal Melbourne to congratulate Day personally.
"He said that he was going to see his friend Kel Nagle and he was going to tell his friend about what he saw today," Day said of the 84-year-old.
"I replied I'd love to have five British Opens, too. He said 'At least get three'. So I have to kind of fulfil my promise there one day."
