The Irish teenager, 18, joined Rory McIlroy’s record after winning the tournament in which he started at odds of 150/1

The youngster started the week as a 150/1 outsider to lift the trophy on his tournament debut, but wrote his name in the record books with a 2&1 victory over Colm Campbell at County Sligo.

Holmes is the youngest winner of the tournament since McIlroy’s back-to-back wins in 2005 and 2006 as a 16-year-old.

It wasn’t just Holmes’ West of Ireland debut, but also his maiden outing at any Men’s Championship.

Fighting against his opponents and the biblical weather conditions, the student came out on top despite admitting it was “one of the hardest stretches of golf I’ve ever played”.

Holmes revealed that his victory even came as a surprise to him, explaining that he didn’t expect to be in and amongst it.

He said: “It’s incredible, I didn’t really have any expectations coming into this week.

“I played a great first 13 holes, some of the best golf I have ever played, and then I don’t know what happened to the weather but it was worse than the first round which was hard.

“You weren’t making any pars out there the last few holes. You are not able to get to any of the greens, it was ridiculous.

“I guess I’m in with a few good names now so it’s nice. McIlroy is incomparable.”

Despite what was at stake for the teen, Holmes still thought watching idol McIlroy battle for the Green Jacket at the Masters last week was more nerve racking than his own battle on the Harry Colt Championship Links.

He told Irish Golfer: “Watching him in the Masters was terrifying, I guess. He’s my favorite golfer. So, yeah, I guess that’s kind of cool [to follow in his footsteps].

“Watching Rory [was more stressful] – at least you have some sort of control over the situation when you’re doing it yourself.”
