In the space of a single weekend Paul Dunne has managed to become a household name in Ireland, and undoubtedly around the golfing world.
But just exactly who is this mystery man who has experienced a meteoric rise to fame?
Here is what we know so far.
Paul Dunne is a 22-year-old Irish amateur golfer from Greystones, County Wicklow.
He is the only amateur golfer that qualified to play in this year’s widely renowned Open Championship in St Andrews golf course in Scotland.
Mr Dunne is a past pupil of Blackrock College. He also played college golf at the University of Alabama where he obtained a degree in business finance.
The rising star actually qualified for the 2014 Open but was knocked out after his two opening rounds.
Now, he currently sits amongst the best players in the world at the top of leader board.
The Open will finish today and although Paul is in the lead, bookmakers are sceptical that he can pull off the win as he is closely followed by golfing heavyweights including Jordan Speith, Jason Day, Louis Oosthuizen and Adam Scott.
If Paul does win today, he will be the first amateur to win the Open in 85 years. But unfortunately there is a downside. If Mr Dunne secures the win he won't get to take home the €1.8m prize money because of a rule that states amateurs who win don't get to keep the cash.
But with the his new found success and an inevitable flurry of endorsement deals, we think he'll manage just fine!
