Britain's Danny Willett, who was tied sixth at last week's British Open, produced another brilliant performance to lead the way in the European Masters before thunderstorms ended play early at Crans Montana today.
He chalked up nine birdies in a second-round 62 to take the clubhouse lead on 13 under par.
Sharing second place on 12 under were South Korean pair Baek Seuk-Hyun (63) and Yang Yong-Eun (63), the 2009 U.S. PGA Championship winner.
Swedish amateur Marcus Kinhult was in fourth spot on nine under after posting a 66.
"I hit it well on the range this morning, got into a nice rhythm early on and carried it through the whole round," Willett told reporters.
"Over these last two weeks I haven't been getting too far ahead of myself and every time I've got in trouble I've just taken my medicine and moved on to the next hole."
American Patrick Reed (69) was in a group on four under par, one better than Britain's Lee Westwood (69).
Spaniard Sergio Garcia faces an anxious wait before he discovers on Saturday if his one-under-par aggregate will be good enough to make the cut.
Of the Irish; Peter Lawrie shot a 68 to lie on five under, while Michael Hoey followed by yesterday’s hole-in-one-65 with a 73 for two under and Damien McGrane is seven over after 15 for the day and ten over in total.
Twelve groups were unable to complete their rounds before the storms engulfed the Swiss Alps.
