The Australian golfer Adam Scott is the new world number one, ending a 14-month spell at the top for Tiger Woods.
Scott was ranked number two for 38 weeks, but the 33-year-old Queenslander's gone to the top of the rankings list as Woods remains sidelined indefinitely with a back injury.
Last year's Masters champion, who finished in the top five of three of the major championships last year, is only the second Australian, after Greg Norman, to hold top spot.
New Zealand's Lydia Ko missed the chance to take out the top women's world ranking when she finished fifth at the latest LPGA Tour event over the weekend.
A win at the Kingsmill Championship in Virginia would have given Ko the number one world ranking.
