Bramford slips back
Overnight leader Matthew Bramford slipped down the leaderboard after a two-over-par 74 to finish the round in fourth place on five-under, while top-ranked player Christiaan Maas carded a 69 to remain in the hunt on four-under.
Issa Abou Ela matched van der Merwe’s 65 to finish the second round in tied sixth alongside Simon du Plooy on three-under-par.
The Egyptian rolled in eight birdies in a prolific performance, including a near hole-in-one at the 16th, with the only blemish to his card coming with a bogey at the par-5 2nd.
“I can't put into words how hard this golf course is so to be able to shoot 65, honestly, it's a score that I'll never forget,” said Ela.
“I almost had a hole-in-one on 16. I got sent some videos from people back home, especially my family, and realised it just missed the hole. A round like that gives me a lot of confidence and I’ve managed to put myself in position after the second round. I’m looking forward to the weekend and whatever happens, happens.” The cut fell on 14-over-par with 40 players advancing.
