That's such bullshit. Koepka, Dustin, Patrick Reed, Henrik Stenson, Justin Rose, all in the hunt on Sunday morning. It read just like any other Sunday morning leaderboard in a major. Some big names struggled and missed the cut, just like any other major.
Yes, the course was badly set up on Saturday and it was unfair to some players. Not because it was too hard, but because it played like a different course in the afternoon to how it played in the morning. The USGA made a mistake.
But it's not unusual for weather to impact how a course plays. I was at an Open Championship a few years ago and the wind and rain On Thursday afternoon and Friday morning killed a lot of players' chances. Decent weather on Thursday morning and Friday afternoon meant the bulk of the players who made the cut were from that side of the draw. It happens.
