Jason Day has revealed he is using his last-round capitulation at the Emirates Australian Open late last year as motivation for 2018.
Day led into the final round at The Australian in November in his first appearance in the national Open since 2013, but could not close it out, ultimately shooting a two-over par 73 and finishing fifth.
He was overhauled by Cameron Davis, the young Sydney professional who shot a 64.
"I drove it great down there and had a lot of opportunities at winning that tournament and I didn't get across the line, which was really disappointing," Day told Australian Associated Press after his victory in the Farmers Insurance Open today.
"It had been four years since I had played in Australia and I wanted to put on a good show in front of the home crowds, but I didn't do a good enough job and that really frustrated me because I played some good golf at The Australian."
The San Diego tournament at Torrey Pines was Day's first start since the Open in Sydney, and he admitted that his disappointment was driving him forward.
"Being in contention gave me a lot of confidence coming into this year," said Day. "Jordan (Spieth) won the Australian Open and went on to dominate the next year.
"I wanted to use that same platform for myself to be able to do the exact same. I didn't but sometimes with a loss and failing it spurs your on to try even harder."
