Billy Horschel is into the top 15 of the Official Golf World Ranking after winning the FedEx Cup with success at the Tour Championship.
Horschel pocketed the first prize of over $1.4million with victory at East Lake on Sunday, which also saw him earn a $10m bonus as he claimed the FedEx Cup ahead of fellow American Chris Kirk and world number one Rory McIlory.
The 27-year-old carded a two-under final round of 68 to finish three strokes clear of Jim Furyk and McIlroy in Atlanta, marking a second straight triumph following his win at the BMW Championship a week earlier.
And the Floridian has now received further reward for his performance by moving nine spots in the rankings to number 14, leapfrogging former world number one Tiger Woods among others.
Furyk meanwhile has jumped from seventh to fifth and Rickie Fowler, who finished eighth at the Tour Championship, is up one place from 11th to take Phil Mickelson"s position in the top 10.
Kirk has risen two places to number 22 but the big mover of the week is Paul Casey, the Englishman surging up the rankings courtesy of his one-shot win at the KLM Open,
Casey held off compatriots Simon Dyson, Andy Sullivan and Eddie Pepperell to earn his 13th European Tour title, gaining 26 spots to move to number 62 as a result.
