PARIS – Newly-crowned 2018 US Open champion Brooks Koepka climbed to a career-high world ranking of fourth on Monday, after successfully defending his title at Shinnecock Hills with a one-shot victory.

The 28-year-old American, who has missed much of the season with a wrist injury, jumped five spots from ninth in the rankings, while also gaining valuable Ryder Cup points.

Koepka's rise saw Jordan Spieth, Rory McIlroy and Jon Rahm, who all missed the cut last week, drop a place.

England's Tommy Fleetwood moved into the top 10 after becoming only the second man in US Open history to fire a final-round 63 as he finished second on Sunday.

Dustin Johnson retained his world number one status despite seeing his bid for a second major title come up two strokes short, as top-ranking rivals Justin Rose and Justin Thomas failed to launch fourth-round challenges in New York.
