• Seven-shot lead reduced to two by runner-up Dustin Johnson
• Koepka recorded five bogeys in his last eight holes
Seven shots ahead at the start of play, six shots ahead after 10 holes, one shot up on the 15th tee. Brooks Koepka opened US PGA Championship week by insisting majors were the easiest tournaments to win. “You think so, do you?” came the belated response from the golfing gods.
It seems astonishing that Koepka’s successful defence of the Wanamaker Trophy was ever in doubt. Yet in doubt it was as a supposed formality lurched towards disaster.
