Georgia Hall has been handed an unexpected selection to play in the US Women's Open after being "completely unaware" she was first reserve.
The Dorset golfer will line up at Lancaster Country Club, Pennsylvania next month, her first ever US Open.
Hall, 19, thought her chance had gone when she missed out on a place in a five-way qualifying play-off in May.
"When I lost, I was quite upset and disappointed that I had come so close to going," she told BBC Radio Solent.
"I kind of wasn't sure of my place on the reserve list.
"I thought I was just the first in my section, so it was quite a shock when I got the call from an American number on my phone and it was a senior representative at the US PGA."
Hall, who earned her Ladies European Tour card in December, will tee off in the first round on 9 July following the withdrawal of South Korean Se Ri Pak.
It will be her first major as a professional having played at the British Open twice and once at the Women's PGA Championship as an amateur.
"It will be completely different to the British Open," she added. "The greens will be a lot faster and I've got to try and learn as much as possible from the practice rounds.
"I've got to go out there and give it my best and I'd like to say a top-20 finish could happen."
