Philadelphia, PA -- (Sports Network) - Ryuji Imada beat Kenny Perry in a playoff at the AT&T Classic on Sunday and vaulted 20 places to No. 49 in the latest world rankings.

Last week's other big winner, Richard Finch at the Irish Open, moved up 84 places to 134th in the rankings.

Further up, there were few big changes.

The top 20 remained nearly identical from last week, the only changes coming with Jim Furyk's two-spot bump to No. 5, which dropped Steve Stricker and Geoff Ogilvy to sixth and seventh.

Tiger Woods remained No. 1, of course, and was followed by Phil Mickelson, Ernie Els, Adam Scott, Furyk, Stricker, Ogilvy, K.J. Choi, Vijay Singh and Sergio Garcia to make up the top 10.

The next 10 players were Justin Rose, Padraig Harrington, Henrik Stenson, Rory Sabbatini, Stewart Cink, Trevor Immelman, Anthony Kim, Aaron Baddeley, Luke Donald and Lee Westwood.
