MELBOURNE, Australia -- After nearly withdrawing due to a family tragedy, Jason Day made an emotional return to golf at the World Cup to win his first tournament in more than three years at Royal Melbourne on Sunday.
His 7-foot putt to save par on the 16th hole held off a faltering Thomas Bjorn. Day had a 70 for a 10-under total of 274. That was two strokes better than Denmark's Bjorn, who finished with a 71 after two late bogeys.
Day's last victory came at the Byron Nelson Championship on the PGA Tour in 2010, although he's had four top-five finishes in majors since 2011.
The World Cup was Day's first tournament in five weeks and came less than two weeks after he learned that eight of his relatives, including his grandmother, died in the devastating Nov. 9 typhoon in the Philippines.
His mother, who immigrated to Australia from the Philippines 30 years ago, and sister were just off the green on 18 at Royal Melbourne. They both hugged him as he walked to the scoring tent to sign his card.
"It's just been an amazing tournament for me," Day said. "My mother, my family, coming down to support me. I'm just so happy the hard work has paid off, and I'm glad it happened in Melbourne.
"It would have been the easiest thing for me to just go ahead and pull out of the tournament with what has been going on over the last week," he added. "But I really wanted to come down here and play."
Day's situation wasn't lost on Bjorn.
"Obviously a fraction disappointed, I didn't play that great today," Bjorn said. "But I couldn't be happier for Jason winning. He has gone through a rough time of late and for him to even be here is a big thing and then to go and win a golf tournament ... that's what you want to see."
Masters champion Adam Scott finished third after a 66, three strokes behind. Scott, who was trying to win his third tournament in a row, shot a 75 on the opening day, including a 9 on the 12th hole, and spent the rest of the tournament trying to catch up.
Day earned $1.2 million for winning the individual title and helped Australia win the team portion of the World Cup. Day and Scott, who each holed approach shots for eagles Sunday, shared the $600,000 first-place team prize.
American Matt Kuchar shot a 71 to finish fourth in individual stroke-play, three behind Day.
Day led by four strokes after nine holes thanks to a big swing on the fifth and sixth. Day bogeyed the par-3 fifth after going into bunker and Bjorn birdied, leaving them tied for the lead.
But on the sixth, Day's gap wedge from about 80 yards hit the green once and rolled into the cup for eagle. Bjorn, who was in the rough with his tee shot, made bogey and the three-shot swing put the Australian back in the lead.
On the next hole, Day increased his lead to four over Bjorn when the Danish player three-putted for bogey.
After making the turn with the four-shot lead, thanks to a 12-foot par-saving putt on nine, Day ran into big problems on the 10th when his tee shot went into the left rough. Trying to advance it up the fairway instead of chipping out sideways, he sent the ball but back into the rough.
He chipped back out to the fairway with his third shot, put his fourth on the green and two-putted for double-bogey. That reduced his lead to two shots over Scott and Bjorn, and birdies by Bjorn on 11 and 13 put both players level again until Bjorn's bogey on 16.
Scott, who holed out for eagle with his approach on the first hole Sunday, won the Australian PGA and Australian Masters in his first trip back home since winning at Augusta in April. He'll try to complete the Australian `Triple Crown' of majors next week at Royal Sydney.
"It's been an incredible day," Scott said. "Thanks Jason, you played so well this week."
