Rickie Fowler has reached unprecedented Official World Golf Ranking heights following his win in Abu Dhabi, while Jason Dufner's victory at the CareerBuilder Challenge allowed him to cut his world ranking in half.
Fowler jumped two spots to No. 4 in the latest standings after he finished one shot clear of an elite field in the desert, his fourth worldwide victory since May. Fowler had reached No. 5 in the rankings a number of times in recent months, notably after his win at the Scottish Open, but this marks his highest career ranking.
Dufner, meanwhile, survived a sudden-death playoff at the CareerBuilder Challenge to record his first victory since the 2013 PGA Championship. That win at Oak Hill moved him to No. 8 in the world, but his game faltered and he began 2016 ranked No. 135. After a top-10 at the Sony Open, Dufner moved to No. 120 and now jumped another 60 spots to No. 60 with his fourth Tour career victory.
Dufner's opponent in that playoff was David Lingmerth, who continued the strong play he showed in the latter half of last season. This was Lingmerth's third playoff appearance in his last 16 PGA Tour starts, and despite coming up short he moved up 16 spots to a career-best 36th in the latest rankings.
Other movers included Phil Mickelson, who jumped five spots to No. 31 after a T-3 finish in Palm Springs, while Kevin Na moved up three spots to No. 20 after his fourth top-three finish in six starts during this wraparound season.
Thomas Pieters finished alone in second behind Fowler in Abu Dhabi, and as a result the young Belgian vaulted 30 positions to No. 58 while Branden Grace moved to the cusp of the top 10, now ranked No. 11 after his T-5 finish.
Fowler's move was the only change to the top 10, although Rory McIlroy is now within one-tenth of a point of Jason Day for the second slot. Jordan Spieth remains No. 1, followed by Day, McIlroy, Fowler, Bubba Watson, Henrik Stenson, Justin Rose, Dustin Johnson, Jim Furyk and Patrick Reed.
