Nicole Broch Larsen defied miserable conditions in Sweden to take a commanding four-shot lead after the third round of the Helsingborg Open.
Despite persistent, driving rain throughout the day, Broch Larsen cruised to 14 under for the tournament after a five-under 68 which consolidated her overnight lead at the Vasatorps Golf Club.
The Dane carded four birdies and then eagled the 16th after a sweetly-struck three-wood to 10 feet before suffering her only blemish of the round at the last as she failed to get up and down from a greenside bunker.
Broch Larsen is the only player in the field to have broken 70 in all three rounds, and she extended her advantage over Ashleigh Simon, who also bogeyed the last to complete a two-under 71.
"I played very well today and make few mistakes and when I did I fought back," said Broch Larsen, who won twice on the Ladies European Tour Access Series in 2013 prior to her rookie year on the Ladies European Tour in 2014.
"Today I could putt on three of the par fives so it was nice to hit it long and reach the par fives. It's really nice that I kept it going and I'm in the lead so tomorrow is going to be exciting. I don't know what I have to shoot but I'll make a number and go for it."
Simon, who stormed up the leaderboard with a 65 on day two, added: "I hit it good today and didn't hole as many putts as yesterday but that's kind of what happens when you have nine birdies in a round. I'm still happy with the way I played.
"I didn't hit it too good the last three holes but I'm only four behind and Nicole played great so it was good to feed off each other.
"We don't know what the weather's going to do tomorrow. Nicole's had three really good rounds and she's playing really consistent so I'm going to need a good low one to try and beat her."
Denmark's Malene Jorgensen lies in third two shots further back after returning a 69, while England's Felicity Johnson moved to seven under with a solid 70.
