Dean Burmester produced five birdies to take a one-shot lead into the weekend at the European Masters.
The South African began Friday four shots behind first-round leader James Morrison, who hit a course record of 60 on day one in Crans-sur-Sierre.
But the two-time European Tour winner – including success at the Tenerife Open earlier this year – carded an impressive unblemished 65 to move himself to the summit of the leaderboard at 11-under.
"I've played well both days. Today, I was just solid," he said.

"I didn't get off to the best of starts, but holed a nice 10-footer on the first for par. You need those momentum ones; that just set the tone for the day.
"I putted beautifully again today. The greens were a little trickier this afternoon, I think it will be more of the same on the weekend. I'm very happy with today."
A shot behind and tied for second are Andy Sullivan and Belgium's Thomas Detry, who carded 65 for the second day running, while Renato Paratore is a stroke further back in fourth.
