Aussie golfer Jason Day has climbed atop the world golf rankings leaderboard, and is now poised to become one of the greatest golfer in his era, claiming, as good as he is right now, that no other person on earth could beat him in golf.

Day has finally completed his dream of becoming world No. 1 after his runaway victory at the BMW Championship on Monday in Lake Forest. The 27-year-old has won four of his six starts, which includes his first career major title at the US PGA Championship in August.

"I just always had a vision of me standing on top of the earth when I was a kid and knowing that, right now, there's no one on this planet that's better than me,” Day told the Chicago Tribune. “That’s pretty cool.”

Day’s remarkable season has officially labelled him as the best golfer on the planet, but the 2015 US PGA Championship winner is still behind in the list of Australia’s best golfer of all time.

Day is the youngest world No. 1 Australia has ever produced, eclipsing the mark set by Greg Norman when he became the world’s top golfer at the age of 31. However, Matt Murnane of the Sydney Morning Herald recognised that Day still has a long way to go to match or exceed Aussie golfer greats Norman and Peter Thomson, although the Queenslander proved how far he can go in a short period of time when he has the “mentality” to win tournaments.

"Ever since the Open championship [in July] something changed in my head,” Day told the Sydney Morning Herald. “I felt like it was my time to start winning tournaments and ever since then it has just been a phenomenal run.”

Day has won twice in the playoffs, and will head into Atlanta for the Tour Championship as the top speed in the FedEx Cup standings. Day will enter the finale of the FedEx Cup playoffs as world No. 1, after overtaking the lead from Jordan Spieth and Rory McIlroy, and will have the chance to become Australia’s first ever winner of the $10 million (AU$14 million) FedEx Cup prize at the Tour Championship.
