Carl Pettersson jumped 69 places to world No. 61 after winning the Chrysler Championship for his first PGA Tour victory. Pettersson finished with a final- round 71 on Sunday to beat Chad Campbell by one stroke.
Even more significant, maybe, was Paul McGinley's win at the European Tour's Volvo Masters. McGinley went bogey-free over his final 53 holes to beat world No. 6 Sergio Garcia by two strokes and move up eight places to 18th in the rankings.
McGinley's breach was one of just a handful of changes to the top-20 this week.
The first nine places remained the same, with Tiger Woods hanging on to the top spot followed by Vijay Singh, Phil Mickelson, Relief Goosen, Ernie Els, Sergio Garcia, Jim Furyk, Adam Scott and Chris DiMarco.
The only change in the top-10 occurred in the final spot, where Kenny Perry moved up two places into 10th.
Angel Cabrera remained 11th, David Toms dropped two places into 12th, Luke Donald and Padraig Harrington flip-flopped spots 13 and 14, and Colin Montgomerie remained 15th.
Michael Campbell and Davis Love III held onto the 16th and 17th spots, where they were followed by McGinley, David Howell and Darren Clarke.
McGinley bumped Tim Clark from the top-20.
