With five players separated by an average of one point, golf could see its own version of musical chairs with the No. 1 ranking.
This week, Henrik Stenson (No. 3) has his best chance at rising to No. 1 because he is playing in the BMW PGA Championship at Wentworth, which effectively offers bonus points as Europe's flagship event. Stenson should be able to reach No. 1 if he places higher at Wentworth than Scott at Colonial.
"It's definitely on, but I haven't given it too much thought in that sense," Stenson said Wednesday. "I've been more trying to work on my game and try to get back in good shape because I know, if I get my game to where I want to have it, then that's definitely an achievable thing in the near future."
Stenson knows that he may need to be patient.
"I'm more into trying to focus on the processes of playing good golf and giving myself the best chance to become world No. 1," he said. "And if I can win some tournaments this year, I will have a good shot at getting there."
Matt Kuchar (No. 4) would have to win Colonial to climb to No. 1.
This wouldn't be the first time for all the jockeying for No. 1.
The early summer of 1997 featured the most dynamic stretch in the 28-year history of the ranking when No. 1 changed five times in five weeks. Greg Norman was No. 1 until Woods replaced him. Woods lasted one week until Ernie Els won the Buick Classic and went to No. 1. Norman won the FedEx St. Jude Classic the following week to return to No. 1, and then Woods won the Western Open and reclaimed No. 1 for the next nine weeks.
