Following his playoff victory at the John Deere Classic over the weekend, Zach Johnson jumped up to 11th in this week's world rankings.

Johnson had been 17th, but he used a great bunker shot to set up a win Sunday over Troy Matteson and earn the resulting bump in the rankings.

In front of Johnson, the top-10 remained unchanged from last week. Luke Donald remained No. 1 and is still followed by Rory McIlroy, Lee Westwood, Tiger Woods, U.S. Open champion Webb Simpson, Masters winner Bubba Watson, Jason Dufner, Matt Kuchar, Justin Rose and Hunter Mahan.

Johnson's move up bumped Graeme McDowell, Adam Scott, Steve Stricker and Martin Kaymer down one spot each. They sit 12th through 15th, respectively. Phil Mickelson remained No. 16, while Dustin Johnson dropped two places to 17th.

Louis Oosthuizen rose two places to 18th, which dropped Charl Schwartzel and Rickie Fowler down to 19th and 20th.

Jeev Milkha Singh, who beat Francesco Molinari in a playoff at the Scottish Open over the weekend, climbed 105 places to 87th.
