Adam Scott could replace Tiger Woods as the world No 1 if he wins the WGC-Cadillac Championship at Doral this week.
In order to usurp Woods at the top of the rankings Scott would need to emerge victorious over the remodelled Blue Monster course in Miami and see defending champion Woods finish outside the top seven.
However, Scott's bid to become the world's No 1 golfer for the first time could well be aided by the fact that Woods might not even be able to compete this week.
The American withdrew from the final round of the Honda Classic on Sunday after complaining of back spasms and admitted he was unsure whether he would be ready to play at Doral.
"I need treatment every day until Thursday to try to calm it down," Woods said. "We'll see how it is."
If Scott were to achieve the feat, he would become only the second Australian - after Greg Norman - to claim top spot since the rankings were introduced in 1986.
The last of Norman's 331 weeks at number one was back in January 1998.
Scott has put himself in position to follow in Norman's footsteps after a spectacular year on the course that was sparked by his memorable victory at Augusta last April.
After a fantastic run of form in his native Australia towards the end of 2013, when he won the Australian PGA and Masters and was just pipped by Rory McIlroy at the Australian Open, the 33-year-old from Adelaide acknowledged that becoming No 1 was a realistic aim.
"Being world No 1 is more a dream than a goal. It's something I told myself as a kid playing at Twin Waters (as a junior on the Sunshine Coast) or even younger in the street with a plastic golf club that I wanted to be world No 1," Scott said after his victory at the Australian PGA.
"I would love to be No 1 I think it can definitely happen and I think my game is not far from being No 1 in the world."
