Magnus Carlsson of Sweden shot a 7-under 65 on Wednesday to open up a two-stroke lead after the opening round of the Nordea Masters.
Carlsson's round was soured by making a bogey on the last at Bro Hof.
Countryman Peter Hanson and clubhouse leader Richard Bland of England are next along with two others.
The 661st-ranked Bland says "I had a bit of an up and down start but I kicked it into gear around the turn."
Third-ranked Lee Westwood is in a group of eight at 4 under. Playing partner and defending champion Alex Noren shot a 74.
The Nordea Masters started Wednesday to give some players more time to prepare for the U.S. Open next week in San Francisco.
