New USPGA champion Keegan Bradley is up from 108th to 29th in the world rankings - and joins the list of those now ahead of Tiger Woods.
Former number one Woods is now down to 33rd, with his missed cut in Atlanta leading to him being overtaken not only by Bradley, but also Dane Anders Hansen - now a career-best 23rd after his third-place finish - and 18-year-old Italian Matteo Manassero.
Worksop’s Lee Westwood remains second.
Keegan triumphed by one shot in a three-hole shoot-out with American Jason Dufner to claim his first major.
“It feels unbelievable, I can’t believe this trophy is sitting next to me,” said Bradley.
“It seems like a dream and I’m afraid I’m going to wake up here in the next five minutes and it’s not going to be real.”
Westwood’s putting remains the thing that bugs him. He tried a lighter approach to it in Georgia, but still they did not drop often enough.
With so many top-three and top-10 finishes now there is no doubt he has the game, but going so close so often creates its own pressures.
As he headed off to a 10-day holiday in Barbados - his next event is the European Masters in Switzerland from September 1 to 4 - he said: “I have enjoyed playing great for a long time now.
“But unfortunately when I turn up to majors and don’t win one it’s a disappointing week for everybody it seems - and obviously for me.
“That’s the sort of level of golf I’m playing at.”
Westwood has played 55 majors in his career.
