Mahan soared 10 spaces to No. 4. He will look to ride that momentum into
Augusta this week in hopes of winning his first major championship.
The top three players -- Luke Donald, Rory McIlroy and Lee Westwood -- were
unchanged from last week. Behind Mahan, Steve Stricker remained No. 5, while
Martin Kaymer dipped two to sixth.
Tiger Woods, Charl Schwartzel, Justin Rose and Webb Simpson all fell one place
apiece and are now seventh through 10th. Jason Day and Dustin Johnson stayed
put in 11th and 12th.
Adam Scott tumbled three notches to 13th, Phil Mickelson inched up one to 14th
and Graeme McDowell slipped a pair to No. 15.
Bubba Watson moved up two places to 16th as Bill Haas and Matt Kuchar dipped
to 17th and 18th, respectively. PGA Champion Keegan Bradley and Nick Watney
exchanged places with Bradley up to No. 19.
