Unfortunately for Luck and the media department of the Australian PGA, Luck's ace occurred at 8:49am on Friday morning and wasn't in front of the well-oiled masses as Koepka's in the beer-mist of Adelaide was.

There was nobody around to video it either.

Yet it was perhaps the better golf shot - a wedge from 124 metres to a sucker pin on a small green which took one hop and spun back into a hole that most pros were aiming well to the left of.

Luck said that as the ball set sail for the hole it was always going to be close. He looked it up and down. All he was thinking was "don't go too long."

"Then I saw it land and I was confident it was going to stick pretty close. But it spun back a little bit and went in the hole. Pretty electric stuff.

"Then the immediate rush of adrenaline kicked in and I nearly broke my playing partner’s hand.

"There were a few guys watching but it wasn’t too busy that time of the morning. And I don’t think anyone got it on camera, which sucks.

"Blame the PGA!" Luck joked.

The ace kick-started Luck's round and he fired a second consecutive 67. He credited his wedges and "golf IQ".

"My wedge play this week has been unbelievable. I've been doing a very good job of playing somewhat to the safe side of the holes but still being aggressive, because it was tough on golf courses like this that are severe around the greens.

"It’s tough to not get in the habit of playing away from the flags. I think I’ve done a good job when I’ve had those ‘green light’ moments to be aggressive."

One of those was on 17.

"My original statement to [caddy] Duane [Smith] was I was going to hold one just to the right of the flag," Luck said.

"The wind was off the right but there was no moment that I was thinking ‘flag’.

"I said to him if I hit this 10 foot left of the hole it would be an amazing result.

"But fact is I hit a really good wedge and it might not have turned on the wind as much as I assumed.

"But it was a great golf shot.”

Luck, who began his round on the back nine, revelled in conditions that that became ever harder as the sun and wind did their thing.

Indeed he felt he could've gone lower.

“I had a lot of putts ended up right over the hole. But having a hole-in-one to kickstart it back on track when you’re one-over, in pretty tough conditions, was what I needed and I just managed to stick with it.

"It’s a golf course that suits me because it’s not overly penalising off the tee, and then you’ve got to be very smart with your golf IQ hitting into the greens, which is one of my strengths."

When informed that his mate had aced 17, Lucas Herbert's eyes lit up.

"How good's that. His shout for the beers tonight! We've got a late tee-time [on Saturday] as well!" Herbert said after shooting six birdies in his 68.
