Bubba Watson is hopeful of a good showing at the Players Championship this weekend but admits the top spot in world golf is an unrealistic target.
The Masters champion is one of four players in the Sawgrass field who could relieve Tiger Woods of his No 1 ranking with victory in the $10m 'fifth major'.
But, boasting a best finish of 37th in six outings at the Florida track, Watson, who is playing his first tournament since his Augusta victory, admits a remarkable turnaround in fortunes is unlikely.
"I haven't played very well around here," he said. "I was looking at my record at Sawgrass before I came... three missed cuts, a 50-something place and two 30-somethings.
"Around this golf course it's very challenging for me and when I look down holes like the first and the 10th it's hard to tell the difference between the fairway and the rough."
On his chances of claiming the No 1 spot, Watson said: "Let's look at the numbers. My best finish here is 37th - just write that down - 37th, so unless 37th moves me to No 1 we probably don't need to worry about that.
"Phil Mickelson, who is arguably top-five best of all time, has never been No 1 which shows me the rankings are kind of messed up so it won't ruin my life or my career if I never get there."
But Adam Scott, who along with Henrik Stenson and Matt Kuchar could assume the mantle of the 'world's finest' with victory on Sunday, admits heading the rankings has been a long-held ambition.
"It's impossible not to think about it," said the Australian. "It would be a dream come true to make it to that point."
