Buchanan's exemption for The Open this summer will see him return to a venue he previously attended as a fan.
“I believe the first Open that I went to was at Royal Birkdale in 2017 so to go back somewhere I was a kid watching not too long ago is going to be really special. Kevin Na gave me a golf ball that he got a hole-in-one with in a practice round. Rickie Fowler gave me a signed glove," he said.
“My favourite golfer since I was a kid has been Rory McIlroy, so just to see him up close would be pretty cool. Obviously you have some of the South African names too.”
Verster, who led after day one, attempted to put some early pressure on Buchanan at the start of final round with an opening birdie. However, any momentum was halted when he dropped two shots on the following hole with a double-bogey.
A run of five birdies in nine holes was brought to a halt with another double at the 17th, but the 22-year-old bounced back with a birdie at the last to finish the day with a three-under-par 69.
While Verster’s challenge faltered, Barnard and de Bruin surged up the leaderboard – de Bruin with the lowest round of the week. The teenager managed 10 birdies on Saturday, almost aced the par-3 12th and finished his round by draining a huge eagle putt on the 18th to vault into second place.
“I'm quite speechless. I just felt like I was floating almost and wasn't there on the course. I was just enjoying it, playing some good golf. Birdies came and that's how all this happened," de Bruin said.
