A closing birdie from Bernd Wiesberger handed him the lead at five under heading into the second round of the Nedbank Golf Challenge hosted by Gary Player.
Here, we take a look at what some of the chasing pack had to say after their opening rounds.
Victor Dubuisson (68, -4)
"I've been very good with my driver. I didn't miss many fairways, maybe one or two and, you know, here it's the key to play well. It's only the first round. It's great to start like this because the birdies are not easy to do on this course. The goal this week is really to qualify for Dubai. So I think it's a good way to start the tournament."
Branden Grace (68, -4)
"Even from the beginning, I didn't do anything wrong. Putter was cold. Three-putted the second which was costly. Then made a decent bogey on three and three-putted the fourth, so the putter was really cold. Gave myself some good chances and managed to make one on seven, the par three, which is a real bonus, tough little hole. Managed to make a few putts, kept hitting the ball great and giving myself chances. It's nice to be able to play in South Africa. It's my first start here this year. I want to make the most out of that one."
Scott Jamieson (68, -4)
"It was a mixed bag, really. A few more good ones than bad ones. I didn't play the par fives particularly well until the ninth hole, our last hole. That was nice to make a birdie. You always want to be under on the par fives here when you can reach most of them. Spain was good, iron play was really good there. I didn't drive it very well the first two rounds last week in Turkey but then played well over the weekend. Just didn't really get it going so, yeah, today was a great start."
Alex Noren (69, -3)
"I played probably the best I've played for a long time. Very steady, a little better off the tee which makes it a lot easier from there on. I'm very pleased. Four under would have been great but I'm happy with three and nobody's kind of running away. It wasn't that easy today, I don't think, and they tucked away some pins. From the start, one was so tight to the edge and that's how they kept it going."
Charl Schwartzel (69, -3)
"It's about as solid as I've played this golf course. I hit the ball beautifully, really could have shot nothing today. You know, would have been happy with four under, the last putt was just terrible. Luckily it's only the first round and got a couple to go. But I hit the ball surprisingly good after being so sick yesterday. I think someone somewhere along the line will shoot a good score. I had a 64 or 63 in me today. I didn't make a putt at all. Somewhere along the line, someone is going to do that and that's probably what's going to separate them. But today, first day, everyone is probably just trying to get something done. That's maybe why it's so congested."
