“It’s a good start,” said Oosthuizen. “I’m hitting it really well. I made nice putts, hit it fairly close the front nine, and probably made one or two longish birdie putts.
“Then teed off on ten and the wind came in, with the weather coming in, and I probably just missed two shots and put myself in really tough spots to get up and down and then made bogey. But I’m feeling good, spinning it well - I haven't hit it that well in a while like I did on the front nine.”
The 29 year old Gonnet, whose best finish in seven years on The European Tour came when he was a runner-up in Scandinavia back in 2007, had completed an outward 32 before the break, then after eight straight pars on the back nine found the par five 18th green in two and two-putted for birdie.
“It was good to put my name up right away, because I haven't played like this for more than a year,” said Gonnet, who had broken 70 only once previously in 2013.
“I played pretty straight off the tee, and my putting was great; five under is a good score.”
Edfors, without a European Tour title since claiming three victories in his rookie season back in 2006, holed a ten footer at the 14th for one of six birdies in his round.
“I was really happy I came out of the block pretty good there on the front nine and played some really, really good golf,” he said.
Defending champion Bernd Wiesberger, playing the back nine first, turned in a three under 33; however, the Austrian had a few putting problems after the resumption and slipped back to one under.
Fleetwood and Oosthuizen, who share sixth place with Ireland’s Peter Lawrie and Korean Jung-hwan Lee, will resume their rounds at 7.30am on Friday morning.
