After 64 weeks as the reigning World No 1, towering Dustin Johnson, in a kind of David and Goliath story, has had to hand over his crown to fellow American Justin Thomas.
Johnson, whose last win of his 17 came at the Tournament of Champions in February and who was fighting to hold off a bunch of hungry pursuers, needed to finish in the top 10 at the Players Championship at TPC Sawgrass on Sunday to keep his crown, but he could do no better than share 17th place.
In the meantime, Thomas, who since January 2017 has won six PGA Tour titles including the 2017 US PGA Championship, closed with a sizzling 66 that saw him elevated into a tie for 11th alongside Tiger Woods and four others and was able to become the new World No 1 for the first time with a lead over Johnson of 0.25 points.
Jordan Spieth, who finished 41st at TPC Sawgrass moved up one slot to 3rd place on the new Rankings list, replacing Jon Rahm who finished near to the bottom of the leaderboard in 61st place.
But Nos 5, 6, 7, 8 and 9, namely Justin Rose, Rickie Fowler, Jason Day, Rory McIlroy (despite missing the cut) and Hideki Masuyama all retained their place with the only other change among the top 10 coming at No 10.
Here Englands Race to Dubai champion, Tomy Fleetwoods, who, as the World No 14, finished The Players in a share of 7th, ousted this year's Masters winner Patrick Reed to break into the World's top 10 for the first time.
And Webb Simpson, who won The Players to capture his first title since 2010 - how did he fare in the updated rankings list?
The 31-year-old soared from No 41 to 20th.
On the side of the Atlantic, Joakim Lagergren, the 31-year-old Swede who won the European Tour's Sicilian Open on Sunday has rocketed from World No 248 to No 133.
