Brooks Koepka returned to the top of the world rankings on Monday after his nerve-jangling second straight US PGA Championship victory at Bethpage Black. The 29-year-old American has now won four major titles in his last eight starts and is the first man to ever hold back-to-back titles in two majors at the same time, ahead of his tilt at a third successive US Open crown next month.

He edged ahead of previous world number one Dustin Johnson at the summit, after his compatriot failed to chase him down in New York on Sunday, finishing two strokes adrift, having been seven behind at the start of the final round. It will be Koepka's ninth week as the world's top-ranked player. Justin Rose slipped down to third due to Koepka's rise.
