Walker vaults to 32 in world rankings

Philadelphia, PA ( - Jimmy Walker claimed his second win of the season at the Sony Open on Sunday, and that victory vaulted him to No. 32 in this week's world golf ranking.

Walker, who earned his first career PGA Tour win at the season-opening open in October, jumped up 15 spots from 47th last week.

The top five players remained the same, with Tiger Woods maintaining the top spot ahead of Adam Scott, Henrik Stenson, Justin Rose and Phil Mickelson.

The first movement inside the top 20 came with Zach Johnson inching up a place to sixth, causing Rory McIlroy to drop a spot to No. 7. Matt Kuchar, Steve Stricker and Sergio Garcia again rounded out the top 10.

Jason Day, Ian Poulter, Jason Dufner, Brandt Snedeker and Graeme McDowell all held firm to sit 11th through 15th, while Jordan Spieth and Dustin Johnson swapped places to occupy 16th and 17th, respectively.

Charl Schwartzel, Luke Donald and Webb Simpson maintained their positions to finish the top 20.

Louis Oosthuizen defended his title at the Volvo Golf Champions on Sunday to move up seven places in the rankings to No. 27.
