Richard Sterne / Getty Images Richard Sterne and Maximilian Kieffer lead the Joburg Open with fabulous first rounds of -8 under par of 63 on Royal Johannesburg & Kensington’s par 71 West Course. Both players now face three rounds on the tougher par 72 East Course, but Richard knows this course pretty well, the South African had a victory here in 2008, the five-time European Tour winner said: " I had three good rounds around the East Course that year. If I can do that now I’ll have a chance on Sunday." Richard suffers from a dodgy back, which held him back during the last two years, he said he never knows when its going to be good; " Some days it feels good and everything kind of happens, golf is strange, you've got to hit the right kind of shots at the right time. I hit 17 greens today, so I was never really in trouble at all." Germany's Maximilian Kieffer continued the impressive start he has made to his rookie year campaign, having already finished tied for fourth in Durban and tied for 17th in Dubai. Maximilian said he enjoyed his great first round here; " When you come from the Challenge Tour everyone says that you have enough to play out here, but you still want to prove it. It’s a new world and you don’t really know what to expect, so I’m happy that it went pretty good so far. That round was great, I've been playing well the last few weeks and I just tried to stay positive on the golf course, and luckily today was another good round." Bryce Easton of South Africa, had a hole-in-one on his way to posting the best round on the tougher East Course, a 65, which gave him third place on -7 under par. Speaking about his hole in one, Bryce said; " It’s one of those things, you don’t think about it when you’re playing the hole, but when it goes in it takes a couple of seconds to realise that it’s actually disappeared." The defending champion Branden Grace, and two-time winner Charl Schwartzel also played on the East Course on day one, but while former Masters Tournament winner Charl opened with a four under 68, Branden could only produce a level par 72.
