Brooks Koepka back to world No.1 with PGA win
American Brooks Koepka is back atop the official world golf ranking after winning the PGA Championship for a second consecutive year over the weekend.
This marks the first time since the start of the year that Koepka has held the No. 1 ranking, which has been shared by fellow American Dustin Johnson and England's Justin Rose over the past 20 weeks.
Koepka now stands ahead of Johnson, with Rose down one spot to No. 3. 
It will be his ninth week as the world's top-ranked player.
No player has claimed their first four Majors as quickly as Koepka, who won back-to-back U.S. Open titles in 2017-18.
The 29-year-old also became the first repeat PGA Championship winner since Tiger Woods in 2007. 
Koepka seeks a third consecutive U.S. Open crown at Pebble Beach next month.
The rest of the top 10 remained the same after the second major of the year, with Tiger Woods ranking sixth.
