After notching his first worldwide win in two years, Tiger Woods is now No. 21 in the Official World Golf Ranking.
Woods won the Chevron World Challenge on Sunday, which offers world ranking points despite the 18-man field. He improved 31 spots in the ranking, earning 40 points for the victory.
It was his greatest single-week haul of points in the last two years. He earned 30 points for falling in a playoff to Graeme McDowell in this same event last year, better than the 27 points he earned for finishing T-4 at the 2010 Masters and U.S. Open.
Woods was last at No. 21 in the world ranking on July 24.
The top four players remain unchanged, though it took a win by Rory McIlroy to keep it that way. McIlroy captured the UBS Hong Kong Open to stay at No. 2. The victory held off Lee Westwood, whose successful defense at the Nedbank Golf Challenge would have otherwise moved him to No. 2.
With his first win in Hong Kong, McIlroy closed the gap No. 1 Luke Donald to 2.05 points.
