Johnson started the year at No. 7 but, after the injury kept him out of tournaments for about three months, he slipped to No. 20. He played in the Memorial and wound up 19th on June 3.
A week later he picked up his sixth PGA title. It is the fifth consecutive year he's had at least one championship.
His move to No. 10 was the only change in the Top 10 the week before the year's second major golf tournament. The U.S. Open is contested this week in San Francisco.
The world's top three ranked players will be in the same group the first two days of the Open. Luke Donald, with a rankings point average of 10.285 is No. 1 followed by Rory McIlroy (9.013) and Lee Westwood, who was a winner by five strokes at the European Tour's Nordae Masters on Sunday, is third at 8.163.
Martin Kaymer (5.016) falls two places from 10th to 12th, leaving Steve Stricker (5.030) in 11th.
