South African Jacques Blaauw, who signed for a 63, led the field at 13-under par.

Blaauw, 34 and with four wins on the South Africa PGA Tour, grabbed an eagle and seven birdies in his round to be one shot clear of fellow South African Wilco Nienaber who added a 67 to his opening 63 for a 12-under par tally.

“I’m very happy I was able to finish,” said Blaauw.

“I hit it very well all day and then made some putts. I only made one bogey so I’m very happy. It was very windy out there, but I found it didn’t affect my distances that much,” said Blaauw, who is searching for his maiden European Tour title after coming close with a second-place finish in the 2015 Tshwane Open.

“I can’t think ahead because there are two more rounds to go. Golf is the job and I need to get that job done. But I’ve done some good work in the build-up to this tournament and I’m very happy with how it’s turning out.”

Blaauw’s putting in particular stood out, with playing partner Scott Jamieson declaring, “I’ve never seen somebody putt as well as he has for the past two days.”

“I’ve switched to the arm-lock putter and I’m very happy with it,” said Blaauw. “I’m looking forward to the weekend. It’s a bit different without spectators, but I’m looking forward to it.”

Ardglass Cormac Sharvin capped his round with a 13th hole eagle ‘3’ but was left ruiing taking a quadruple ‘8’ at his 11th hole in his round of 74 to miss the cut at one-over par
