Jason Day has revealed his trip to Royal Birkdale for the 146th Open Championship was inadvertently delayed due to American president Donald Trump.
Day, who has endured a disappointing year to date after topping the world rankings for much of 2016, planned to fly to England on Sunday.
However, a change of plan followed as a result of Trump's attendance at the U.S. Women's Open in New Jersey.
"I had three weeks off before this, so I could have got in early," said Day as he explained his Monday morning arrival in a news conference.
"I was actually supposed to get here Sunday. And I was flying through JFK and president Trump was there and there was a bunch of delays. So I just decided to move my flight back a little bit later."
Asked if he had ever previously been held up by a head of state, a grinning Day replied: "I have. President Obama held me up one time flying out of Palm Springs.
"So I understand. It is what it is. It was massive delays. They were stopping and starting, so I just didn't bother with it. And it was quite nice, I got to spend more time with the kids at home.
"Usually I do get in here to places like this early. I usually get in Thursday or Friday and play a couple of practice rounds. I did it this year at Augusta and I was just truly knackered by the time I started on Thursday.
"I got some work before I came in here. I think all in all I feel pretty ready and fresh going into [Thursday's] round."
Day's best Open finish came in 2015 at St Andrews when he tied for fourth with Jordan Spieth.
