The 18-year-old from Hawaii bogeyed her first hole but recovered with a stretch of three birdies in four holes midway through her round and a fourth birdie later at the Golfpark Gut Haeusern course northwest of Munich.
Lora Fairclough of England, the 1998 German Open winner, had a 68 to take the lead at 10-under 134 at the $390,000 tournament on the Ladies European Tour.
Wie was one shot off her score of 68 from Thursday.
It was very frustrating today like yesterday. I didnt really take advantage of the par-5s, Wie said. But I felt like my drives were more solid today and I feel more confident with my shots now. I just hope I can shoot lower scores tomorrow.
I was really patient with myself. It was a little bit frustrating in the beginning. I had a lot of putts early and wasnt able to put them in. But I felt like the middle of my round I really pulled it together. I think I just played solid and played better than I did yesterday. And hopefully I can do that tomorrow and the day after as well.
Wie was about to size up a 10-foot birdie putt on her final hole when tour officials ordered the final 30 players still on the course into the clubhouse, where they would remain for about two hours while two thunderstorm fronts passed through. Wie was short on the putt and finished with a par.
If we could have just held it off for 2 more minutes I would be out of here and in my bed right now. But the weather is the weather. Its dangerous because of the lightning. I think they really made a good call.
Neither of the other Americans playing made the cut.
Laura Tereby started the day double-bogey and bogey on her way to a 3-over-75 after shooting par on Thursday. Beth Allen improved three strokes to a 73 despite a double-bogey and bogey late.
