After round one of the US PGA Championship at Oak Hill in New York was cut short due to darkness, American Bryson DeChambeau holds the clubhouse lead.

DeChambeau had a four-under 66 to take a one-shot lead over Scottie Scheffler, Dustin Johnson, and Corey Conners.

Both Masters champion Jon Rahm and England’s US Open champion Matt Fitzpatrick battled and shot six-over 76s.

Unheralded American Eric Cole is the leader on five under par, but the 34-year-old has just played 14 holes.

Cole will return alongside 11 other groups on Friday at 07:00 local time (12:00 BST) to complete his round. England’s Justin Rose will also start early, with a 20-foot birdie putt on the 15th to move to two under.

Adam Scott and Dustin Johnson, both former Masters champions, were among the late starters. They battled for the lead and reached to four under before both missed shots on the 18th as they raced to finish in near darkness.

Johnson finished on three under following his first bogey of the day, while Australian Scott finished on two under after a double-bogey six at the last.

DeChambeau, who famously bulked up before outmuscling Winged Foot – a course compared to Oak Hill – to win the 2020 US Open, looked at ease in his opening round, making six birdies and only two bogeys.

Rory McIlroy, the defending champion, fought illness to shot 71, one better than defending winner Justin Thomas.

The start of the 105th US PGA Championship was delayed by one hour and 50 minutes due to overnight frost on the course in Rochester, New York, near the Canadian border. When the music started, this iconic and tough track quickly ramped up the fire.
