Carly Booth, Carin Koch, Caroline Westrup and Stefanie Michl each shot five-under-par 67s to share the first round lead at the UniCredit Ladies German Open.
Booth, who won her first Ladies European Tour title at her home event in Scotland three weeks ago, made five birdies on the back nine at Golfpark Gut Häusern near Munich to grab a share of the lead after a two-hour weather delay mid-afternoon.
"It was just trying to be patient. It was a slow front nine: was only level par through nine but then birdied 10 and 11 and nearly holed my shot on 13 and tapped in for birdie. I parred 14, 15 and 16 and then birdie, birdie to finish," said Booth, 19.
"It was just very solid, especially my last nine. The front nine I missed quite a few putts so I could have been a lot more under par but I left a lot of putts short. I'm happy with today's round."
Sweden's Koch, who tied for third in Turkey a fortnight ago, mixed seven birdies with two bogeys.
"It's really fun to play good golf and I really like this golf course so it's nice to come here and play well," she said. "I played pretty steady today and made some good putts which you have to if you're going to shoot a low score. I'm happy about my game."
Michl had a bogey-free round containing five birdies and said: "I played pretty solid. I hit loads of greens and I hit some quite close. I had a lot of chances for birdie and I just had two up and downs that I made."
Westrup's 67 matched her third-round score from the same tournament 12 months ago, when she earned a career best finish of equal seventh in the event.
She said: "I'm pleased. I left a few birdie shots out there but I played solid off the tee and my irons were my strength today. I rolled in some putts when I need to and hit good shots, so gave myself a lot of opportunities.
Swede Pernilla Lindberg and Czech teen Klara Spikova were a stroke back on four under.
There were 14 players a further shot back, two shots off the lead, including defending champion Diana Luna.
Luna won last year's tournament without any blemishes in four rounds, but ended her bogey-free streak with her first in 93 holes at the 'unlucky 13th'.
