(CNN) -- South African Anthony Michael continues to lead the Alfred Dunhill Championship after the second round at the Leopard Creek Country Club.
Michael posted a three-under-par round of 69 for a 36-hole total of 135, to remain clear of Englishman Robert Rock (70) and compatriots Alex Haindl -- who carded a best-of-the-day 66 -- and Dawie van der Walt (70).
"I got off to a pretty good start and that took some of the pressure off," the 25-year-old rookie Michael, who only turned professional last year, told the official European Tour website.
"I felt comfortable out there and there was a sense of belonging for me. So all in all, I'm quite happy," he added.
However, there was disappointment for British Open champion Louis Oosthuizen, who missed the cut after adding a 71 to his opening round 76.
Oosthuizen has been wearing a brace on his leg after tearing ankle ligaments while hunting three months ago, and this latest setback follows his poor showing in last weekend's Sun City Challenge, where he was the only one of the 12 competitors to finish over par.
The event is co-sanctioned by the European Tour and South African Sunshine Tour and is the opening tournament in the 2011 Race to Dubai.
Meanwhile, Denmark's Iben Tinning and England's Melissa Reid share a one-stroke lead heading into the final round of the Dubai Ladies Masters.
The pair are tied on 208 (-8) after Reid carded a third round 68 and Tinning went around the Majlis course at Emirates Golf Club in 69.
