World number two Henrik Stenson shared the lead with England's world number 346 Eddie Pepperell after the third round at the Nordea Masters in Malmo.
Stenson shot the best round of the day, an eight-under-par 64, to move to on 13 under overall and lead the way with Pepperell, who shot a 65.
The home favourite racked up seven birdies and an eagle two at the seventh alongside one bogey to put himself in pole position ahead of the final day.
Pepperell (23), whose only professional victory to date came on the Challenge Tour two years ago, fired eight birdies and looked set to finish the day with the outright lead, only for a bogey at the 17th to drop him back.
Scotland’s Stephen Gallacher and Spain’s Alvaro Quiros were a shot off the pace.
The former shot a 65, also picking up eight birdies and a bogey, while Quiros went round in 66.
France’s Victor Dubuisson and Welshman Bradley Dredge were also well-placed on 11 under and 10 under respectively.
Michael Hoey is best of the Irish on three under after a 69, while Kevin Phelan dropped back to two under with a 73 and Shane Lowry's 72 meant he remained level par alongside Gareth Maybin (74).
Peter Lawrie is one over after a 72.
