Ted Potter, Jr. earned his first career PGA Tour title on Sunday and that helped him soar in this week's world rankings.
Potter jumped from No. 218 to No. 83 thanks to the win at The Greenbrier.
At the top of the rankings, there was little change. Luke Donald remained No. 1 and was again followed by Rory McIlroy, Lee Westwood, Tiger Woods, U.S. Open champion Webb Simpson and Masters winner Bubba Watson.
Jason Dufner and Matt Kuchar exchanged places with Dufner up to seventh. Justin Rose remained No. 9 and was trailed by Hunter Mahan, Graeme McDowell, Adam Scott, Steve Stricker and Martin Kaymer.
Dustin Johnson inched up one to 15, which bumped Phil Mickelson down one to 16th. Zach Johnson stayed at No. 17 and was followed by Charl Schwartzel, Rickie Fowler and Louis Oosthuizen.
