Philadelphia, PA – In his second event after returning from a back injury, Dustin Johnson closed with a four-under 66 to win by a single stroke at the St. Jude Classic and that helped him leap 10 places to No. 10 in the world rankings.
The win was Johnson's first of 2012 and first since last year's Barclays. In a topsy-turvy season, Johnson is the 17th different player to move into the top 10 this year.
Ahead of him, the top nine remained the same. Luke Donald was followed by Rory McIlroy, Lee Westwood, Tiger Woods, Bubba Watson, Matt Kuchar, Justin Rose, Hunter Mahan and Jason Dufner.
McIlroy will defend his U.S. Open crown at The Olympic Club this week, and Westwood is coming off a five-stroke win last week in Sweden.
Steve Stricker remained No. 11, while Martin Kaymer tumbled a pair to 12th. Phil Mickelson, Webb Simpson, Charl Schwartzel and Louis Oosthuizen all dipped one spot apiece.
Adam Scott stayed put in 17th, Zach Johnson tumbled two to 18th, Jason Day held steady at 19 and Rickie Fowler slid a pair to 20th.
