Louis Oosthuizen shares the lead with Markus Brier heading into the final round of the Africa Open after a four under par round of 69 on day three handed him a 13 under total in East London.
The reigning Open Champion recorded four birdies, an eagle and two bogeys - the second of which frustratingly came on the last - to sit alongside Austrian Brier, who managed a 70, on a tournament total 206.
The pair are a shot clear of a quartet of players on 12 under.
Amongst them are Manuel Quiros (68), defending champion Charl Schwartzel (68) as well as South Africans Jaco van Zyl (70) and Jbe' Kruger (67).
Promising Englishman Chris Wood also carded a six under 67 in the third round, an effort that saw him climb to 11 under, alongside Branden Grace (72) and fellow countrymen Ross McGowan (71) and Miles Tunnicliff (72).
Bristol golfer Wood, who shot to fame in 2008 when he was the top amateur at The Open Championship held at Royal Birkdale where he finished fifth, had a wretched start to his round with a bogey on the par five first.
However, the 23 year old was back level on his next hole before four further birdies and an eagle helped him come back in some style.
The round of the day belonged to Robert Dinwiddie after he went around the East London Golf Club bogey-free through his 66.
That put him on ten under overall and kept him in the hunt for the €158,500 top prize at the co-sanctioned European Tour and Sunshine Tour event.
But Dinwiddie and all of the chasing pack will have to fight hard to catch leaders Oosthuizen and Brier.
Speaking after his round, South Africa's World Number 21 was disappointed not to have gone even better than his 69 and was hoping for more wind to help his game on Sunday.
He said: "It's disappointing with the weather, 66 I thought was an easy number out there today.
"I hit a few good putts, but there were quite a few bad ones as well, so it was very inconsistent.
"But it's a good position to be in ahead of tomorrow, so let's see what happens then."
Brier won the last of his two European Tour titles in 2007 but only kept his card by the skin of his teeth at November’s Qualifying School.
He rolled out two birdies, an eagle and a solitary bogey in round three, all of which left him happy with his day's work.
"It was a good solid round, I didn't make any mistakes, except for 16," he said. "That's the game plan I had more or less for the whole week - stay away from trouble and you get your chances - so it was okay."
