Branden Grace won in his native South Africa on Friday and that helped him jump 13 spots to No. 49 in this week's world rankings.
Grace started the year 271st in the world, but has soared inside the top 50 thanks in part to three wins earlier this year on the European Tour.
The top eight in the rankings remained the same with Rory McIlroy followed by Tiger Woods, Luke Donald, Lee Westwood, Justin Rose, Adam Scott, Bubba Watson and Webb Simpson.
Brandt Snedeker and Jason Dufner exchanged places with Snedeker up to 9th. Steve Stricker inched up one to No. 11 and that bumped Louis Oosthuizen down to 12.
Dustin Johnson held steady in 13th, while Matt Kuchar moved into the 14th spot. Keegan Bradley dipped one to No. 15 and was followed by Phil Mickelson, Zach Johnson, Graeme McDowell, Sergio Garcia and Hunter Mahan.
