English duo Aaron Rai and Paul Waring carded matching rounds of 65 before bad weather forced play to be suspended in the first round of the Joburg Open.
Playing just the third European Tour event of his career, Rai fired seven birdies in a flawless round on the East Course at Royal Johannesburg and Kensington, with Waring recording nine birdies and two bogeys.
That left the pair two shots behind clubhouse leader Paul Peterson, the left-handed American completing a brilliant 62 on the West Course before heavy rain, on an already-saturated course, forced play to be abandoned for the day.
