(CNN) -- Tjaart van der Walt will seek to upstage two of his most illustrious golfing compatriots and win his first professional tournament at the Africa Open on Sunday. 

The 37-year-old goes into the final round tied for the lead with 2010 British Open champion Louis Oosthuizen and one shot ahead of two-time U.S. Open winner Retief Goosen after carding a superb eight-under-par 65 in East London on Saturday. 

Van der Walt, who finished second in a 2005 U.S. PGA Tour event, eliminated Oosthuizen's two-shot overnight lead as he started with four successive birdies and -- like his fellow South African -- picked up a shot at the final hole. 

The world No. 347's only blemish at his home event came at the par-four eighth hole, and he was confident he could contend for his first title since turning pro in 1996 in the opening event of the 2012 European Tour season. 

"At the end of the day, the golf ball doesn't know that they are major champions," he said of his rivals. "I've played at the highest level, I've never won majors or big events, so who knows what can happen. 

"I do feel as if I am controlling the golf ball as well as I have in a long time. Not just tee to green, but on the greens as well. And that's a good sign for me. I'm entitled to forget the one bad shot I hit all day." 

Defending champion Oosthuizen's only lapse came at the par-five 11th hole as he took four shots to reach the green.
