England's Matt Fitzpatrick distanced himself from the pack with a flawless 65 to set an imposing clubhouse target on day two of the Nordea Masters.
62 players were separated by just four shots after the first round at Bro Hof Slott Golf Club, with Fitztpatrick one shot off the six-way tie for the lead following an opening 68.
But after firing seven birdies and no bogeys in ideal conditions on Friday, the 21-year-old from Sheffield found himself with a three-shot lead over former Ryder Cup star Nicolas Colsaerts, with France's Thomas Linard another stroke back.
Peter Lawrie is best of the Irish on one under after shooting a level par second round.
A three over round of 75 leaves Wicklow’s Paul Dunne on one over, just outside the projected cut.
"It's always nice to have a bogey-free round and particularly seven under," said Fitzpatrick, who claimed his first European Tour title with a wire-to-wire victory in the British Masters at Woburn last year and was seventh in the Masters in April.
"More often than not it might be bogey-free and one or two under, but to have seven birdies today is a nice start to the tournament.

"I just gave myself a lot of chances today. Everyone will probably laugh when I say it but I missed a couple of chances on 13 and 14, so roll those in and all of a sudden you are nine under, but I just putted really solidly and played well overall."
Colsaerts has not won since claiming the Volvo World Match Play Championship in 2012, a success which led to being selected as a wild card for the 'Miracle at Medinah'.
But the 33-year-old has shown consistent form in recent weeks and believes the course on the outskirts of Stockholm suits his game after carding five birdies and an eagle in his 66.
Colsaerts told Sky Sports: "It's almost like apart from a few holes, I don't care where I hit it. I can fly a few bunkers and even if I am in the rough I don't really care much. There's only the par fives where you need to take a bit more of an aggressive line because that's the only thing you have.
"I have a good memory of this place from a couple of years ago. I know where I can miss it, which was pretty much the plan and I've followed it for the first two rounds.
"I won't say I'm coming to my best again but everything seems to be heading in the right way. I keep a lot more momentum in the rounds than I used to. I feel like I have always played decent, it was just those momentum breaks that I did not really manage very well and now I do and it puts me regularly in a good position."
