Frustrating day
For van der Merwe, it was a day of highs and lows as the South African mixed an eagle and five birdies with four disappointing bogeys and a frustrating double-bogey at the par-5 13th on the way to a 71.
The 27-year-old is aiming for back-to-back wins after winning the Golf RSA International Amateur at Houghton last week and remains in the hunt for the championship.
“I started very well, but I would say through 9,10 and 11, it was pretty poor and I lost focus,” said van der Merwe.
“We were three good friends playing together, so we tried to build each other up. All of us had good holes and all of us had bad holes. I tried to be more aggressive and it bit me around the turn. The putts just didn't fall like they did yesterday and when I ran it over the lips a couple times, I got frustrated.
“I'm not trying to think about winning at this point. First, I’ve got to do some chasing against two good friends. It's going to be tough, but there's going to be no mercy between us when it comes to golf, so I think we're all going to go for it.”
Simon du Plooy shot a 67 to keep himself within sight of the leading group on eight-under-par, while Zimbabwean Matthew Bramford sits a further two shots back in fifth place after a 71.
