Goosen stood at 12-under 132 at the Golfclub Munchen Eichenried. Soren Kjeldsen of Denmark trailed by one after a 65. John Daly shot 70 for a 144 total, missing the cut by three strokes.
David Drysdale of Scotland had the lowest round of the day, finishing with a 64. Hes tied for third with Nick Dougherty of England (65).
Dougherty had two eagle 3s within four holes. He hit the flagstick with his 6-iron approach to the par-5 sixth hole.
Goosens biggest challenge was coping with the sandflies swarming around the course after three days of heavy rain earlier in the week. Goosens lime-green shirt seemed to attract the flies.
At times they were all over me and I could not see the ball, he said. Eventually, I had to put my blue rain top on even though the sun was shining.
The 24-year-old Kjeldsen, winner of last years Volvo Masters and the Andalucian Open in Spain in March, has risen to No. 37 in recent months. He didnt play at the U.S. Open because of an ear infection.
