The top-10 remained the same from a week ago. Tiger Woods, who just finished a stretch of five events in five weeks in three countries, remained the top- ranked player.
Vijay Singh held onto the No. 2 position and was followed by Phil Mickelson, Retief Goosen, dunhill championship winner Ernie Els, Sergio Garcia, Jim Furyk, Adam Scott, Colin Montgomerie and Chris DiMarco. Kenny Perry stayed put at 11, but there were a few changes after him.

Michael Campbell, who finished alongside Harrington, remained in the 15th spot. Angel Cabrera tumbled four places to 16th, while David Toms dipped one to 17.
Davis Love III and Darren Clarke exchanged positions from last week with Love taking 18 and the Ulsterman dropping to 19. Tim Clark remained in the 20th slot again this week.
