Rory McIlroy dropped to two and Justin Rose improved two spots to No. 3. Luke Donald and Brandt Snedeker both fell one place to fourth and fifth respectively. Louis Oosthuizen held steady at No. 6 and was followed again by Adam Scott, Steve Stricker and Matt Kuchar.
Keegan Bradley shared third behind Woods at Bay Hill and improved four notches to 10th. His moved pushed Phil Mickelson, Ian Poulter, Lee Westwood and Bubba Watson down to 11th through 14th.
Charl Schwartzel improved two to 15th, while Graeme McDowell and Sergio Garcia both slid a pair. Jason Dufner, Webb Simpson and Dustin Johnson closed out the top 20 again this week.
