Amateur Christiaan Mass fired his second-successive five-under-par 67 on Tuesday as he moved into a strong five-point lead after the second round of the IGT Tour’s Chase #8 Revised Stableford at the Els Club Copperleaf.

Players have swapped the usual stroke-play with a revised Stableford format which awards points for under-par scores and deducts points for over-par scores. Under this format, which promotes attacking golf, a birdie earns you two points, an eagle earns five and an albatross is an eight-pointer. A par earns you a zero. On the other hand, a bogey means minus one point and a double-bogey will be a minus three.

Maas made an eagle, five birdies and two bogeys to rack up 13 points. Together with the 14 he made in the first round, his 27 put him five clear of Kyle McClatchie, who made just one bogey on his way to a 67 of his own.

“I like this format because lately I’ve been making a lot of birdies which is ideal,” said Maas. “It’s fun to play, especially as I’ve hit the ball really well and my driver was going very straight but my putting wasn’t the best.”

Round of the day belonged to Louis Albertse, who made nine birdies and just one bogey on his way to a superb 64. That gave him 17 points, moving him to 20 for the tournament and into third spot, poised to try and strike in the final round.

Maas will try and keep doing what he has been doing in an attempt to keep his grip on the lead. “I’ll just play the course like I play it normally and stick to what I have been doing and stay aggressive,” he said. “My driving and my irons were solid the past two rounds, and, if I can make some putts, it should go well.”
