Two other winners over the weekend moved into the top 50 after their victories -- with Andalucia Open champion Niclas Fasth moving up 11 spots to 46th and the Crowns (Japan) winner Shingo Katayama skipping eight places to 43rd.
Further up the list, the top 20 remained virtually unchanged.
Tiger Woods remained the No. 1 player in the world, followed again by Phil Mickelson, Retief Goosen, Vijay Singh and Ernie Els to round out the top five.
The next eight places were identical to last week's rankings, with Sergio Garcia holding onto the sixth position, followed by Jim Furyk, David Toms, Adam Scott, Luke Donald, Chris DiMarco, Jose Maria Olazabal and Henrik Stenson.
The first change to the top 20 came at the 14th position, where Chad Campbell supplanted Tim Clark. After that flip flop, Geoff Ogilvy held on to the 16th position and was again followed by David Howell at 17.
Kenny Perry moved up one spot to 18th, Fred Couples jumped four places to 19th, and Rory Sabbatini advanced one slot to 20th. The movement by Couples and Sabbatini knocked Darren Clarke and Colin Montgomerie out of the top 20.
