A first Open appearance for England's Toby Tree will be a true debut as he has never attended a major either as a fan or a player.
The 23-year-old booked his place at Royal Birkdale in a 72-man qualifier at Woburn last week, posting the same six-under score as Ryder Cup star Ian Poulter on his home course.
And while he was a member of Europe's 2012 Junior Ryder Cup team defeated at Olympia Fields in Chicago nothing will come close to teeing it up against the world's best on the Southport links.
"I've never been to a major championship either as player or spectator," Tree, who plays most of his golf on South Africa's Sunshine Tour and the European Challenge Tour when he is not at Goodwood in West Sussex, told Press Association Sport.
"I played the Junior Ryder Cup when I was 18 in America and we had an exhibition match on the (Medinah) course behind the main teams who were playing their practice rounds and the crowds were pretty big.
"On that first tee you had a similar thing (to the Open) where they announce your name and it was lined each side of the fairway three back and the stands were full.
"I suppose that is the only thing I can relate to so I'll just have to go with the flow when I get there.
"It is a big opportunity to play on a big stage and I am looking forward to performing at that level against the best players in the world.
"The Challenge Tour is tough and not as glamorous but if I give myself the opportunity to have a good week it could be life-changing."
Tree followed up his successful Open qualifying tournament with an eighth-placed finish at the Prague Golf Challenge on the European Challenge Tour so heads into the week in reasonable form.
He has high expectations of himself but may have to rein in his naturally aggressive approach which almost cost him dearly at Woburn.
"I shot four under in the morning and got to nine under (helped by two eagles) in the afternoon," said the 2014 Welsh Amateur Champion, who turned professional at the end of that year.
"The 12th was a driveable par four and I thought it was going well so I may as well just keep going but I probably should have laid up as it was qualifying.
"I went for it, made a bogey and then a couple more to make it a bit tense so I could have made it a lot easier for myself as nine-under would have easily qualified.
"I play quite a lot in South Africa and when I first turned pro if you wanted to play in the co-sanctioned events with the European Tour there were qualifiers with 10 spots from 100 people and my first season down there I qualified for four out of five so I got a nickname as the qualifying specialist."
