Soderling defeated Gael Monfils in Sunday's final in Paris. The 1,000 rankings points for the title boosted Soderling's total to 5,380 points and edged him past Andy Murray, who was beaten by Monfils in the quarters and has 5,360.
That puts Soderling at No. 4, a position he's never before attained, and he's less than 300 points behind No. 3 Novak Djokovic heading into the ATP World Tour Finals next week in London.
Murray fell to fifth in the rankings. He's been ranked lower than fourth just four weeks since August 2008.
Rafael Nadal, with 11,450 ranking points, is solidly in first and Roger Federer (7,645) is still No. 2.
Tomas Berdych (3,755 points) is sixth followed by No. 7 David Ferrer (3,735) and eighth-ranked Andy Roddick (3,665). The top eight ranked players earn invitations to the world finals.
Fernando Verdasco (3,240) is ninth and Mikhail Youzhny (2,920) is 10th this week.
