Crans Montana, Switzerland – Stephen Gallacher fired a 6- under 65 on Friday to grab a share of the lead after two rounds of the European Masters.
The Dubai Desert Classic winner is joined by 12-time European Tour champion Thomas Bjorn at 10-under-par 132.
"First place is not bad," Gallacher said. "I'm happy with that. It gives me something to work on over the weekend."
Bjorn shot a 5-under 66 during his second round at Crans-sur-Sierre to meet Gallacher atop the leaderboard.
Danny Willett matched the low round of the day with a 7-under 64 to jump into a tie for third place at 9-under 133. He is joined by Victor Dubuisson (65), Richard Finch (66), Tommy Fleetwood (68) and Miguel Angel Jimenez (68).
First-round leader Anirban Lahiri managed an even-par 71 and dropped into a share of eighth place with Brooks Koepka (66), Paul Casey (69), Mark Tullo (66) and Alejandro Canizares (65) at 8-under.
Willett went out with the morning wave and raced to the top of the leaderboard with a bogey-free round that included five birdies and an eagle.
Dubuisson met him at 9-under shortly after when he capped his bogey-free round with his sixth birdie of the day at the 18th, placing the duo a stroke ahead of overnight leader Lahiri.
Their lead was short-lived, however, as Lahiri met them at 9-under with a birdie at the third and pulled ahead with another gain at the third, but then bogeyed the fourth to fall back even with Willett and Dubuisson.
After Lahiri traded a birdie at the seventh with a bogey at the eighth to remain at 9-under, Gallacher birdied the 12th to make it a four-way tie for the lead.
Gallacher poured in his second straight birdie at the 13th to pull ahead of the pack at 10-under.
The Scot moved to 11-under with a birdie at the 15th, while Bjorn jumped into second place at minus-10 with two birdies in a three-hole span from the 12th.
Gallacher then bogeyed the 17th to fall to 10-under and into a tie for the lead with Bjorn and Lahiri, who birdied the 14th.
As Gallacher parred his final hole to end there, Bjorn rolled in a birdie at the 17th to claim the outright lead at 11-under. But Bjorn failed to hang on to the lead and bogeyed the last to finish alongside Gallacher at 10-under.
"I told myself not to make any stupid bogeys this week because everybody's going to do that. I made one down the last, which is the first one, but it is just one of those things," said Bjorn. "I am happy with how I am playing; I played steady without being spectacular."
Lahiri tripped to a double-bogey 5 at the 16th to fall three strokes off the pace and parred his final two holes to stay there heading into the weekend.
