Joburg Open:South African trio Hennie Otto, James Kingston and Jakobus Roos ensured local dominance on the leaderboard after the second round of the Joburg Open.

They were all 11 under after playing both the par-72 West and par-71 East course, with the tournament reverting to the championship East course Saturday.

Australian Terry Pilkadaris, whose six-under-par total took him to 10 under, is fourth while Argentinian Ariel Canete is level at nine under with two more South Africans, Dean Lambert and Louis Oosthuizen.

David Higgins is six shots off the pace, a second round of 69moving him to five under.

Roos posted the best round of the day on the West course, taking a seven-under-par 65. The temperamental Otto went round the course in five under.

Kingston was unhappy with his start, but more than overjoyed with the way he came alive at the end six under par for the day.

On the second hole he hit a five iron to 15 feet and two-putted for the birdie on the par five. At the ninth, his three iron into the green left him with a 30-foot putt, which he sank easily.

A birdie on 17 and eight iron in from 167 feet on the 18th gave him an eagle opportunity from eight feet out, which he took comfortably.

Kingston could not truly explain his relaxed approach and said: "I'm probably still in Mozambique on holiday at the moment. I enjoy the golf courses and I was very surprised yesterday as I hadn't played a lot of golf coming into this week and to start on the tougher of the two courses."

South Africa's Charl Schwartzel, the top-ranked player of the tournament, narrowly missed the three-under cut when he rattled up five birdies on the back nine to shoot a 68 and finish six under for the tournament.

Earlier Frenchman Raphael Eyraud scored the first hole in one of the tournament on the fifth hole, teeing off with a five iron to register the ace.
