Charl Schwartzel's emphatic 12-stroke victory at the Alfred Dunhill Championship on Sunday helped the South African jump nine places in this week's world rankings.
Schwartzel, who won in Thailand by 11 shots two weeks ago, now stands at 14th in the world.
The top four in the rankings remained unchanged from last week as Rory McIlroy was followed Luke Donald, Tiger Woods and Justin Rose.
Adam Scott, helped by Louis Oosthuizen's withdraw from the Alfred Dunhill Championship, leapt two places to No. 5. Oosthuizen dropped a spot to sixth and Lee Westwood was pushed down from sixth to seventh.
Bubba Watson, Jason Dufner, Brandt Snedeker and Webb Simpson stayed put at Nos. 8-11, while Ian Poulter jumped a spot to 12th, which bumped Keegan Bradley down to 13th.
Schwartzel's rise pushed Graeme McDowell down to 15th and Sergio Garcia, fresh off a win at the weather-shortened Johor Open, moved up four spots to No. 16.
Phil Mickelson, Steve Stricker, Peter Hanson and Nick Watney rounded out the top-20.
Thorbjorn Olesen held onto the 50th spot in the rankings and earned a Masters bid as a result.
Also receiving Masters bids were Paul Lawrie (ranked No. 29), Francesco Molinari (30), Gonzalo Fdez-Castano (33), Branden Grace (34), Bill Haas (35), Nicolas Colsaerts (36), Jason Day (37), Hiroyuki Fujita (43), Matteo Manassero (44), Thomas Bjorn (45), Jamie Donaldson (47) and George Coetzee (49).
