Ogilvy began this year as the 50th-ranked player in the world, but is now second on the worldwide money list after victories at the WGC-Accenture Match Play Championship and U.S. Open.
Ahead of the Australian, nothing changed. Tiger Woods missed the Open cut, but remained the top-ranked player, while Phil Mickelson collapsed on the 18th hole to finish runner-up, but held onto the second spot.
Behind Woods and Mickelson, Vijay Singh retained his No. 3 ranking and was again followed by Retief Goosen, Jim Furyk, Adam Scott and Ernie Els.
Of that group, only two-time U.S. Open winner Goosen missed the cut at Winged Foot. Furyk tied for second place with Mickelson and Colin Montgomerie, who received a bump of eight places to No. 13.
Ogilvy's addition to the top 10 dropped four players one spot apiece. Sergio Garcia fell to ninth and was followed by David Howell, David Toms and Luke Donald.
After Montgomerie at 13 came Jose Maria Olazabal and Henrik Stenson to round out the top 15. Olazabal and Stenson each dropped two places.
Stenson was trailed by Chad Campbell, Tim Clark, Stuart Appleby, Darren Clarke and Chris DiMarco. Of that group, only No. 20 DiMarco did not lose ground from last week's rankings.
Elsewhere, Cesar Monasterio of Argentina won the Aa Saint Omer Open on the European Tour and climbed 277 positions to 285th in the world.
