BAD GRIESBACH , Germany (AFP) - Bernd Wiesberger surged into the early lead at the European Open in Germany with an eight-under-par 63 on Thursday (Sept22) and vowed there would be no repeat of last year's calamity.

The Austrian made a sensational start to the European Tour tournament for a second year in a row to lead by two strokes from Italy's Renato Paratore, on a day when more than three hours of play were lost to fog early in the morning at Bad Griesbach.

Wiesberger opened with a 64 in 2015 but followed that with a 76 to miss the cut.

"I'm thinking more of what happened today, keep pushing and playing the game I played today. What happened a year ago, it was a weird week and I know I'm not going to repeat that tomorrow," said Wiesberger, 30.

"Obviously I played alright, but had a couple of shots that cost me, believe it or not. I hit it out of bounds on the first hole after I made a good turn, struggled a little bit.

"But I hit a lot of good shots, a lot of good putts and I'm happy with how I played today." Paratore turned in 34 after three birdies and a double-bogey but came to life on the back nine, making an eagle on the 10th and birdies on the 13th, 14th and 15th.

"Today was a really good day," he said. "I started really nicely, two under after four holes.

"Then I made one double-bogey but after that I played really well, especially with the putter."

Lucas Bjerregaard, Daniel Im and Steve Webster had all held the lead before Wiesberger's late charge and they finished the day at five under.
