With many of the world's best players taking the week off, the top 10 remained virtually unchanged. Tiger Woods maintained his stranglehold on the No. 1 spot and was again followed by Phil Mickelson, Retief Goosen, Vijay Singh, Jim Furyk, Ernie Els and Sergio Garcia.
The only change to the top 10 was at the eighth and ninth positions, where David Toms moved up one spot to replace Adam Scott, who was then followed by Luke Donald at 10th.
Jose Maria Olazabal remained 11th, Chad Campbell and Henrik Stenson flip- flopped places 12 and 13, with Campbell moving up, and Tim Clark moved up three spots to 14th.
Geoff Ogilvy jumped one slot into the top 15, while Chris DiMarco and David Howell each slipped two places to 16th and 17th, respectively. Stuart Appleby remained 18th and Darren Clarke replaced Davis Love III at 19th, dropping Love one place to round out the top 20.
Also over the weekend, Thomas Bjorn won the European Tour's Irish Open with birdies on his final two holes. The victory moved him up three places to No. 30 in the world.
