Top-ranked Tiger Woods, who has been idle since his second Masters triumph two weeks ago, still held a huge lead over No. 2 Phil Mickelson in the points-based ranking. They were followed by Ernie Els, Lee Westwood, Colin Montgomerie and Vijay Singh.
Singh, who notched his PGA Tour-leading seventh top-10 finish Sunday with a tie for sixth at the Shell Houston Open, is currently second on the PGA Tour money list behind Woods despite having no victories.
David Duval, who tied for 26th Sunday sits in seventh place, while Davis Love III dropped one place to eighth. Shell Houston Open winner Hal Sutton, who will be on hand to defend his title this week at the Greater Greensboro Classic, remained in ninth place.
Darren Clarke of Northern Ireland, a joint leader heading into the final round of the European Tour's Spanish Open, struggled to a 79 on Sunday that included a quintuple-bogey 10 at the par-five 15th hole. He slipped from eighth to 10th in the latest rankings.
Sweden's Jesper Parnevik dropped one place to the 11th position, while Jim Furyk moved up a spot to 12th. Canadian lefthander Mike Weir, Tom Lehman and Denmark's Thomas Bjorn rounded out the top 15.
Nick Price, ranked 17th last week, climbed to 16th in an exchange of positions with Sergio Garcia. Mark Calcavecchia and Michael Campbell also traded places, with Calcavecchia jumping to 18th and Campbell dropping back to 19th.
Ireland's Padraig Harrington stayed in 20th place.
