Ian Poulter claimed his second World Golf Championship title on Sunday and that helped him jump 11 spots in this week's world rankings.
Outside of the top six, there was plenty of movement.
The top six in the rankings remained the same with Rory McIlroy followed again by Tiger Woods, Luke Donald, Lee Westwood, Justin Rose and Adam Scott.
Jason Dufner moved up three to No. 7 thanks to a share of second behind Poulter. Webb Simpson dipped one to eight, while Brandt Snedeker held steady in ninth.
Louis Oosthuizen inched up one to 10, while Bubba Watson was down three to 11th and Steve Stricker held steady in 12th. Phil Mickelson, who finished alongside Dufner, was up six spots to No. 13 and Keegan Bradley stayed at 14.
After Poulter, Nick Watney was 16th again, but Matt Kuchar was down four to 17 and Dustin Johnson slid three to 18th. Peter Hanson dropped a pair to 19th, while Ernie Els, who also tied for second behind Poulter, was up four places to No. 20.
Zach Johnson and Sergio Garcia both fell three spots to drop out of the top 20 this week.
