Robin Williams signed for a 7-under 65 marred by a single bogey at the par-4 3rd hole to take the first round lead at the Alfred Dunhill Championship.

"It was pretty fun out there, I played pretty well. I took advantage of the par fives and the short holes, and I putted well today," said the 22-year-old South African.

"It is all a learning curve for me, trying to see what my game needs in order to make cuts and compete with these guys.

"I put more pressure on myself than really I think there is and it's about learning to handle your emotions, and all of this is just an experience to learn, how to handle not only your game but your emotions in these big events.

"It is a massive confidence boost. I can always say that I shot 65 around Leopard Creek, I will always have that for the rest of my life. I can sleep happy tonight."

Spain's Nacho Elvira and South Africa's Jayden Schaper both also made a bogey and lie a shot back at 6-under.

Scotland's Scott Jamieson double bogeyed the par-5 15th and closed with a 67 for a share of fourth place at 5-under alongside five other players.
