Dufner collected his first major tournament title -- his third PGA title overall -- with a two-stroke victory Sunday at the PGA Championship. Dufner finished two strokes ahead of Jim Furyk and three better than Henrik Stenson.
Dufner set a course record Friday with a 7-under-par 63, a score that tied the lowest score in a major tournament.
That allows Dufner to go from 21st in the world rankings to No. 8. Among those he passes is Graeme McDowell, who slips from eighth to No. 9 in the rankings.
Also in the Top 10, Adam Scott, who led after each of the first two rounds and wound up tied for fifth in the championship. He moves ahead of Justin Rose for No. 4 in the rankings. Rose slips to fifth.
Stenson, 53rd at the start of the year, moves up one place to 10th.
Luke Donald, second in the first ranking of 2013, drops two rungs to No. 11 after missing the cut at the PGA Championship, and Keegan Bradley, who was third at the PGA a year ago but ended up tied for 19th Sunday, falls from 10th to 12th.
