Montgomerie climbed up eight places to No. 9 after the victory. This marked Montgomerie's first time in the top 10 since the second week of 2003.
Tiger Woods remained in first for the 369th week. Vijay Singh, Phil Mickelson, Retief Goosen and Ernie Els rounded out the top five. Els returned to action at the Nedbank Golf Challenge in Sun City this week and finished ninth.
Sergio Garcia stayed in sixth, followed by Jim Furyk, who won the Nedbank event with a chip-in during a playoff. Adam Scott once again came in eighth.
Monty moved into ninth and several players fell in the process. Chris DiMarco, Kenny Perry, Padraig Harrington, Luke Donald and David Howell all fell one place to accommodate Montgomerie's ascension.
Reigning U.S. Open champion Michael Campbell held pat at No. 15. Angel Cabrera and David Toms both slipped a spot, while Davis Love III, Darren Clarke and Tim Clark all kept their places from last week.
