Joachim B Hansen set the early pace as the first round of the Joburg Open got under way at a wet Randpark Golf Club on Thursday morning.
The largest field of the European Tour season had gathered in Johannesburg to tackle two courses at the venue and it was Hansen who made the early running on the Firethorn Course.
The Dane turned in 31 and then added another birdie on the tenth to get to six under, a shot clear of England's Matthew Baldwin, South African Keenan Davidse and Indian Shubhankar Sharma.
Tuesday's pro-am was cancelled due to a flooded course and further heavy rain in the area had softened the courses up but a blustery wind was proving a test for the field.
Hansen is a two-time Challenge Tour graduate and he made four birdies in a row from the second before adding another on the ninth and holing a lengthy left-to-righter on the tenth to hit the front on his own.
Baldwin made eagles on the par five first and 12th on the Bushwillow Course, adding two birdies and a bogey in his first 13 holes.
Davidse was also playing Bushwillow and had six birdies and a bogey in his first 14 holes, a feat matched by Sharma in his first 15 holes over Firethorn.
Home favourite Bryandrew Roelofsz was the clubhouse leader at four under, with Mark Foster, Ross McGowan and Carlos Pigem also in that group.
