Woods increased his advantage over Vijay Singh for the top ranking from 4.88 last week to 5.98 this week. His victory at the NEC represented the ninth WGC title of his career and fifth victory this year.
Phil Mickelson retained the No. 3 ranking he earned with a win at the PGA Championship two weeks ago, while Ernie Els held on to fourth place despite being out for the year with a knee injury.
Retief Goosen and Sergio Garcia remained fifth and sixth, respectively, while Chris DiMarco moved up six places to No. 7 after finishing second to Woods at the NEC.
That dropped Adam Scott into eighth, where he is followed by David Toms and Kenny Perry to round out the top-10. Perry moved up one spot from 11th last week.
The movement in the top-10 meant that Padraig Harrington and Jim Furyk lost ground, with Harrington falling three places to 11th and Furyk getting bumped two spots to 12th.
Angel Cabrera dropped one spot to No. 13 and Davis Love remained 14th, while Luke Donald and Fred Couples each moved up to fill spots 15 and 16, respectively.
Rounding out the top-20 are Tim Clark, Darren Clarke, Michael Campbell and Thomas Bjorn. Clarke fell three spots from last week.
Making a positive move on the list was Vaughn Taylor, whose title defense at the Reno-Tahoe Open moved him up 39 places to 91st in the world.
