The incident, captured by another fan and posted to social media, came as Koepka and playing partners Shane Lowry and Rickie Fowler made their way toward a tee at Quail Hollow Club. As Koepka walked past a tent about 25 yards away, a fan was overheard saying this:

Koepka, who has won the PGA Championship three times, has struggled recently at the major championships — which is becoming a trend for many who opted to join LIV Golf. Koepka didn't finish better than T26 at any of the four majors last season, and he missed the cut at the Masters last month.
