Tiger Woods remained a solid No. 1, but his lead over second-ranked Mickelson was down to 11.15 average points one week after he led Jim Furyk by 13.16 points. Furyk dipped to No. 3 to make room for Mickelson's move.
Adam Scott and Ernie Els held steady in the next two positions, while Henrik Stenson and Vijay Singh exchanged places with Stenson up to sixth. U.S. Open champion Geoff Ogilvy, Retief Goosen and Luke Donald rounded out the top 10.
Sergio Garcia, who finished second behind Mickelson at THE PLAYERS, jumped three places to 11th. To make room for Garcia's jump, Padraig Harrington, Trevor Immelman and Paul Casey each were down one.
Masters winner Zach Johnson remained in the 15th position this week. Rory Sabbatini bumped Charles Howell III from 16th to 17th, while Stewart Cink was up three to 18th after sharing third at THE PLAYERS.
Steve Stricker, Nick O'Hern and David Toms each dropped a notch to make room for Cink's leap. Toms fell out of the top 20 to 21st.
Lee Westwood won on the European Tour and vaulted 15 places to 48th this week.
