Brooks Koepka managed to grab the spotlight from playing partner Tiger Woods while conquering notorious Bethpage Black.
Koepka has a one-stroke lead over Danny Lee through one round of the PGA Championship.
Koepka delivered a 7-under 63, making him the first player in 101 years of the PGA Championship to shoot that score twice.
He broke the course record at Bethpage Black and became the first player to post 63 at a major in consecutive years.
Koepka is the defending champion and is seeking his fourth major championship.
Woods opened with a pair of double bogeys on the back nine and ruined a torrid start to the front nine with a pair of three-putt bogeys.
He signed off on a 72 after carding even par or better in his previous 12 rounds in majors.
