Holywood teenager Tom McKibbin notched his fifth career hole-in-one en route to a five-under 67 that left him just three shots off the lead at the DP World Tour's Investec South African Open in Johannesburg.

 The Newtownabbey rookie (19) followed an opening birdie with two bogeys but after turning in one-under after birdies at the fifth and ninth, he holed a five-iron at the uphill, 224-yard 11th for an ace.

He went on to birdie the par-five 13th before hitting his tee shot inside three feet at the 197-yard 17th at Blair Atholl Golf & Equestrian Estate.

"It was very good," said McKibbin, who is tied for seventh, three shots behind South Africa's Thriston Lawrence, who equalled his course record with an eight-under 64. "Obviously, we've had a bit of luck after the turn, but I played really solid after the third hole onwards. It was just a really, really good day."

As for his hole-in-one, he said: "It was just a perfect five iron and my caddie Chris said, just go right at it. So I went right at it and it didn't really leave the flag.

"Obviously, you can't really see it as it's uphill. But I just heard everyone cheering and we knew it was in, so that was pretty cool."

Fellow rookie Gary Hurley (29) was pleased to continue his hot form by making four birdies in a bogey in a 69 that leaves him tied 25th as Kinsale's John Murphy shot a two-over 74 to lie 126th.

"It was very solid, to be honest," said the West Waterford man. "It was extremely hot at times, which made it a little hard to focus, but I was strong with my behavioural processes all day, allowing things to just happen."

McKibbin is looking to win the second-oldest national open in golf, and he loves the challenge of playing at altitude.

"Yeah, it's it's really good," said the Challenge Tour graduate, who was tied for 18th in last week's Joburg Open. "It's long. It's very challenging. You've got to hit it in the right position, especially in the greens because some of them are really big.

"I seem t play quite good out here (in South Africa). The altitude is obviously quite a tricky thing, especially when it gets windy. You've got to really trust it. 

"But I enjoy playing out here. The ball goes quite a long way. You could be 190 yards out and you're only hitting an eight or a seven iron, so it definitely makes a difference."

As for the history of the event adding extra pressure, McKibbin said: "Not really. I'm just here to play another number tournament and see how good I can do. Obviously, it's a very big tournament. So it does add a wee bit of spice, but I'm just here to see how good I can play. I'm looking really looking forward to it. As I said, the course was great. I think it suits me quite well. So looking forward to the next few days."

A putting tip from his father helped Lawrence equal his course record.

The South African matched the eight-under-par 64 he shot here in a Sunshine Tour event over a year ago for a one-stroke lead over England's Ross Fisher and Swede Jens Fahrbring.

"I'm quite familiar with this golf course. I played nicely and managed to drop a few putts thanks to a tip from my father," said Lawrence.

"After last week's Joburg Open, my dad asked me for some time on the putting green and said I wasn't looking comfortable and should stand a bit further away from the ball. He told me to just trust him, which I did, and it helped."

It was the perfect start for Lawrence on a golf course that by its sheer length challenged the field on a warm day in Africa.

"It's a very long golf course, but I like to play full shots into the greens. I think my mid-to-high irons are the key to my game. It is a long golf course, but it suits me. 

"I'm sticking to my game plan and being aggressive off the tee. I love playing aggressively, and this golf course gives you that opportunity. And to start like this in my national Open means everything. Everybody wants to get their hands on that trophy, and it's a good start."

Lawrence has just come off a rookie DP World Tour season in which he won twice and became the first South African to be named the Sir Henry Cotton Rookie of the Year. And he's clearly picked up from where he left off in this new season.

"I just kept doing what I'm doing. I'm a big believer in not changing what works. I've been doing the same things for the last few years and am a big believer in not changing what's already working."

Fahrbring, who admits he's not a long hitter, put everything into his opening 65 to be one off the lead alongside Fisher. "I tried to hit my driver as hard as I could and today, it went straight and fairly long for me. I hit some quality iron shots and made some putts, which was good. I'm quite tired, so home, rest, get some food and drink a lot of water," he said.
