Woods, who won the Buick Open as a tune-up for this week's PGA Championship, has been in first for a total of 226 weeks. That record comes up well short of Greg Norman's record of 331 total weeks atop the rankings but he continues to keep a strong grip on No. 1.
Phil Mickelson remained in second place, followed by British Open champion Ernie Els, while Retief Goosen and Sergio Garcia rounded out the top five.
David Toms will defend his PGA Championship title starting Thursday at Hazeltine National. Toms once again came in sixth place in this week's rankings.

Vijay Singh, the 1998 PGA champion, moved up one spot to ninth while David Duval, the last player to be ranked first since Woods' stranglehold on the top spot, dropped to 10th.
Jim Furyk climbed one notch to 11th, followed by Nick Price, who dipped to 12th. Bob Estes moved up two places to No. 13 and Michael Campbell fell one to 14.
Colin Montgomerie jumped two spots to 15th and Chris DiMarco also rose two places to 16th. Darren Clarke fell one to 17th while Angel Cabrera plummeted four notches to No. 18.
Scott Verplank, who will make his Ryder Cup debut next month, joined the top 20 when he came in 19th this week. Scott Hoch, an American teammate of Verplank's at the Belfry, completed the top 20.
