Stenson moved up four places to world No. 10 with his victory at the Dubai Desert Classic over competitors like fourth-ranked Ernie Els and top-ranked Tiger Woods.
He is only the 65th player to reach the top 10 since the rankings were born more than 20 years ago.
Baddeley, meanwhile, took advantage of a late collapse by Jeff Quinney to win the FBR Open for his second PGA TOUR title. The victory moved him 46 places to No. 44 in the world and earned him a place in the WGC-Accenture Match Play Championship.
Woods, of course, remained No. 1 in the world and was followed again by Jim Furyk, Adam Scott and Els. Retief Goosen moved up a spot to No. 5, bumping Phil Mickelson to No. 6, while Vijay Singh, Luke Donald and Padraig Harrington held on to places 7-9.
Stenson's move to 10th bumped Geoff Ogilvy, Sergio Garcia, Trevor Immelman and Paul Casey down one spot apiece into Nos. 11-14.
The rest of the top 20 remained the same: David Howell, Nick O'Hern, Davis Love III, David Toms, Colin Montgomerie and Chris DiMarco all held on to their positions.
