It's become a case of the survival of the fittest in the African Amateur Stroke Play Championship after a day of carnage at Leopard Creek.

Overnight leader Ryan van Velzen began the day with a seven-shot lead on 14-under and ended it tied with compatriot Martin Vorster, the reigning East of Ireland champion, on three-under.

The teenager dropped nine shots in a brutal three-hole stretch, six of them going as he pumped three balls in the water at the par-three seventh and ran up a sextuple-bogey nine en route to an 83.

The South African pair lead by two strokes on three-under-par from Amateur champion James Sugrue, who was leading on his own for a spell until followed two bogeys with a triple-bogey seven at the 16th in a 78 that leaves him two behind, alone in third place on one-under.

Punishing pin positions, sweltering heat and a capricious, 30 km per hour wind made Leopard Creek such a beast that just seven of the 84-strong field broke par, and the 54-hole cut fell at 15-over par.

Three of those sub-par rounds came from Irish players with Carton House's Keith Egan unlucky to finish a shot outside the cut mark after a 71 and Matthew McClean rallying from a second-round 82 with a 70 to share 24th on eight-over.

A 71 for Dundalk's Caolan Rafferty catapulted him from 16 shots off the lead to just four back on one-over after a round featuring a bizarre hole-in-one after a "duffed" wedge from 148 yards at the 12th.

"I got the yardage, picked a club, and tried to hit a shot," said Rafferty, who is tied for fifth. "It was one of those funny ones. I didn't really catch it and turned away in a bit of disgust. 

"As I was turning back, I heard my playing partner telling it to go in, and I was like, 'Sorry, that can't be right!' And as I turned round, it just disappeared!"

Sugrue was less than thrilled with his 78 after a late triple-bogey left him with a sour taste in his mouth for the second day running. 

He played the first 13 holes in a creditable one-over-par, but after bogeys at the 14th and 15th, he took six at the par-three 16th. After finding sand over the green, he watched his tricky recovery trickle through the other side into the water, then plugged when forced to drop in the bunker to play his fifth.

"It was pretty windy today and it was also extremely warm," the Corkman said after making just one birdie compared to eight in his second round 68.

"There were also some cheeky pin positions out there, so it was playing tough. Maybe not [78 tough]. My score wasn't a great reflection. But it was probably a few shots tougher than yesterday.

"Caolan teed off just in front of me and it looked like he hit a five-iron, so I took one club less and flew the green into the bunker. When I got into the bunker, it looked like a tricky bunker shot, but I probably didn't give it the respect it deserved.

"I hit it onto the green, and it just trickled, trickled, trickled across the green into the water. Then I had to drop it in the bunker again, and it plugged. So I just hacked it out sideways and two-putted for a triple. It was a triple without really hitting a bad shot, so I am not happy about that one.

"With a triple, you have to make three birdies to get those shots back and today birdies were hard to come by. And for it to happen on my third last hole, I didn't have much chance of getting it back.

"I am playing well, but today, the ball wouldn't go in the hole, I missed so many putts."

Holywood teenager Tom McKibbin is tied for 14th on five-over after an excellent 73 featuring three bogeys and two birdies while Naas' Robert Brazill complete an impressive comeback from an opening 84 by following a 72 with a 73 that featured an eagle three at the par-five 18th — sweet revenge for the nine he made there on the first day.

Brazill made the cut with a shot to spare, but Hermitage's Rowan Lester missed out by two strokes after an 82.

The Dubliner took nine at the par-five 15th and while he fought back with birdies at the 16th and 17th, he could only par the last on a day when Massereene's Tiarnan McLarnon suffered badly and signed for a 94.

Team South Africa stormed through the half-gap given them by Team South Africa Junior to race a five-stroke victory in the team competition thanks to two-under-par 70s for Casey Jarvis and Samuel Simpson and Vorster's four-over 76.

Team Ireland was able to edge ahead of England for third place in the team contest thanks to Sugrue, McKibbin and Rafferty.

Overnight leader Van Velzen was cruising along at level par after the sixth and then simply imploded. 

"I was playing nicely up until then," he said of his nine at the seventh. "I tried to go for the flag, and just came out of it and blocked it right in the water. I dropped one and goofed it in the water again; dropped another and hit it in the water again; knocked it on and two-putted.

"That just rattled me for the rest of the round. I didn't really know what was going to come when I hit it. It was like a lucky packet," he laughed.

Vorster also found conditions tough, but he kept himself in the game as he made three birdies in eight holes coming home to offset the three bogeys and two doubles.

"It was a grind today," he said. "I actually hit the ball pretty well, but some shots just didn't go my way and I ended up making doubles. In the conditions, I'm happy with the way I actually played."

Like many of the overseas players, Sugrue found conditions made playing well difficult. 

Jarvis is one stroke behind Sugrue in fourth going into the final round, and Simpson shared fifth with Rafferty, England's Olly Huggins, who carded a level-par 72, and South Africa's Jordan Duminy.

"I'm very proud of the boys," said captain Kyle De Beer, who was a last-minute call-up after former number one Jayden Schaper joined the paid ranks at the Sunshine Tour's Limpopo Championship.

"We overcame a huge deficit and we were quite dominant in the team side of things today. It's a tough stretch to finish on that back nine, because conditions were so tough and that makes the win that much more special."
