It will be my major debut and I am really excited,” he said. “It’s amazing. I have been wanting to play in a major championship ever since I started playing golf, so my dream finally came true.

Twice a runner-up on the circuit as well and has had six other top five finishes.

Made his PGA Tour debut at last October’s CJ Cup in his home country – his fourth place on the Korean Tour standings at the time earned him a place - and made the halfway cut in the event that saw Brooks Koepka win and become world No 1 for the first time.
