His demeanor is not what you might expect from a player who will tee off in his first major championship later today. If there are nerves, he’s not showing them. Sure, he’s excited but at this point in time he’s just hungry and takes another bite of his sandwich.

The 23-year-old is one of 39 Open Championship debutantes playing at Carnoustie this week. A fraction of that number, including Davis, has never played a major.

Of course, Davis is here in Scotland after shooting a final round 64 to win the Australian Open last November. It was his first victory after turning professional a year earlier. His 11 under total left the likes of Jason Day, Cameron Smith and Jordan Spieth in his wake.

Now golf’s biggest stage beckons and the Sydneysider says he’s ready.

“I’ve played a couple of 18-hole rounds around here and played pretty well, I’m seeing it pretty well,” Davis said. “I’ve got my game plan figured out. I just need to try and pay attention to the stuff I’m doing and stick to the process I’ve placed for myself … that’s all I can do.

“I could sit here and look around at all the players that are here, the guys on the range next to me and stuff, but I feel like I’ve earned my spot here, I deserve to be here.

“If I play some good golf I’ll hopefully have a chance, that’s all you can do, control what I can control.”

Davis has rediscovered the form in practice this week that helped him win the Australian Open as well as the Nashville Open, on the Web.com Tour, in May. In Nashville, Davis closed out with a seven under 65 to claim the title and further his claim for a Top-25 money list spot and a promotion to the PGA Tour for the 2018-2019 season.

With the first round of The Open now only hours away, he still can’t believe how the past eight months of his career have unfolded.

“I never thought it would go the way it has,” he said. “You always wonder how you’re going to get your first win and your second win and anything like that.

“You’ve got no idea of when or where. I’ve just had two great weeks where everything kind of fell together.

“I’ve always felt I could play that way, but it was just whether I could put it together for four rounds. That was something I needed to improve and it was kind of cool to see that if I did it for four rounds it was good enough to win a tournament. It was a big confidence booster.”

"It’s just a matter of constantly hitting the greens, having putts for birdie over and over again. String lots and lots of those together until eventually one will go in and then eventually another and that’s the sort of rhythm you want for a week like this I can imagine." – Cameron Davis.

Davis arrived in Carnoustie last Saturday and immediately got to work on putting together a game plan, which he says is simple and will hopefully be effective.

“I’ve got a feeling the guys that are saying they’re going to bash driver are going to start playing irons off the tee after a little bit,” Davis said.

“There are a few more things that can go wrong with the driver obviously. It seems like the kind of golf course where, although the rough is not long and you can hit the green out of the rough, the ball is going to be tumbling so much when it hits the ground you will have to land a long way short to keep the ball on the green.

“I think if you can just hit fairways with a 4-iron and go into the greens, the middle of the greens, with a short iron and just keep doing that for 72 holes you’re going to shoot some pretty decent scores.

“If you’re in the fairway you can land your ball on the green, it’s just easier. The greens are pretty flat, but the surrounds have a little bit of slope so landing your ball short of a green from the rough you can’t predict how the ball will bounce.

“The ball is rolling so far out there you can hit a normal 4-iron and it will go 270 metres and you only have 9-irons and wedges into the greens after that.

“To my eye, just take the pot bunkers out of play with an iron and give yourself constant short irons into the green, which is more than enough to build a good score and keep the big numbers off the card. It’s just a matter of going out there and executing that plan.”

The 2015 Australian Amateur Champion believes the scoring will be relatively low, which adds to the strategy he will be adopting.

“It’s just a matter of constantly hitting the greens, having putts for birdie over and over again,” he said matter-of-factly. “String lots and lots of those together until eventually one will go in and then eventually another and that’s the sort of rhythm you want for a week like this I can imagine. This is my first major and so I haven’t really experienced a week like this before but that’s how I imagine you need to get through 72 holes on a difficult golf course.”

Davis will be the first of the eight-strong Australian contingent out on course for the first round. He is paired alongside American Brandt Snedeker and Scottish amateur Sam Locke.
