World No 2 Henrik Stenson carded a superb eight-under 64 to climb into a share of the lead at the Nordea Masters.
The home hero and pre-tournament favourite fired seven birdies and an eagle on Saturday to post 13-under par and will go into the final day tied at the top with England's Eddie Pepperell.
That duo are one clear of Scotland's Stephen Gallacher and Spain's Alvaro Quiros.
With Friday's strong breezes having dissipated at the Malmo venue, scoring was much lower and Stenson cashed in with an outward 31 that included an eagle at the long par four seventh when he holed his eight-iron approach shot from 155 yards for an unlikely eagle two.
Stenson followed a birdie at the 11th with another from five feet at the 14th and, after dropping his only shot of the day at 15, closed with two more birdies to post the clubhouse lead of 13-under.
The Swede said of his eagle: "It was a lovely eight-iron. I felt as soon as I struck it that it was going to be inside 10 feet more or less and it landed five feet short, took a little hop, a little release and in she went.
"I guess it all started with a six-iron to about four feet on the previous hole so two great shots and it was a bonus to hole one.
"I played really nicely. There was much less wind than yesterday but still enough to keep it honest. It's a tight leaderboard and I'm sure the lead will change hands more than once tomorrow."
Pepperell started out with a hat-trick of birdies and then caught fire again on the back nine with five more in six holes from the 11th.
That took him into the lead on 14-under but he missed a short putt for par on 17 and had to scramble his five on the 601-yard 18th after finding water off the tee.
That meant he signed for a seven-under 65, a score matched by Gallacher, who reeled off eight birdies and a lone bogey at 17.
Quiros eagled the par five opening hole for the second day running, this time from six feet, and added further birdies at 3, 10, 11 and 14.
He also bogeyed 17 after a clumsy three-putt but got the shot back on the 18th after two big blows to the green.
Victor Dubuisson, the Accenture Match Play finalist earlier this year, was another who threatened to tie the lead after a run of five birdies in seven holes from the 8th.
Back-to-back bogeys at 15 and 16 halted his momentum but the Frenchman holed a good birdie putt at 17 before making par at the last to card a 67 and finish on 11-under - just two back.
