Magnus Carlsson produced a stunning round of 65 to open up a two-shot lead on day one of the Nordea Masters in Stockholm.
The 31-year-old sank eight birdies to go round the course in seven under, although his mood was dampened slightly by a bogey on the last hole.
Carlsson was one of four Swedes on the leaderboard at Bro Hof as the local favourites made the most of home advantage. Peter Hanson was in a group of four players tied for second on five under, with five birdies sitting alongside a single bogey on his card.
England's Richard Bland, the early clubhouse leader, also completed his round in 67, mixing eight birdies with a bogey and a double bogey on the par-five 13th.
Bland's compatriot Matthew Baldwin also put on a solid display of six birdies and a bogey to finish the day five under, along with Spain's Ignacio Garrido.
World number three Lee Westwood led a group of eight players on four under, alongside Swedish pair Michael Jonzon and Robin Wingardh. Michael Hoey is the best of the Irish on two under, with Shane Lowry a shot further back.
Fisher missed out on the Wales Open title last weekend after being hit with a one-stroke penalty and #6,000 fine for slow play when only one off the lead with four holes to play.
Defending champion Alex Noren was in the same starting group as Westwood but had to settle for a two-over 74.
