Scott Hend will take a three-shot lead into round four of the Omega European Masters after the weather-affected third round was completed on Sunday morning.
With two hours and 24 minutes lost on Saturday at Crans-sur-Sierre Golf Club due to heavy fog in the mountains, most of the leading challengers had to return to finish their rounds, with the final group of Hend and Darren Fichardt left with five holes to play.
The Australian entered the day with a two-shot lead at 11 under and he was the only one of the leading pack to make progress in the remaining holes, moving to 12 under to lead the way from Paraguay's Fabrizio Zanotti.
Dane Lucas Bjerregaard, Swede Alexander Björk, South Africans Dean Burmester and Fichardt, Australian Marcus Fraser and England's Matthew Fitzpatrick were then at eight under.
Hend is looking for redemption after losing in a play-off here last season to Alex Noren while Zanotti is seeking a second European Tour title of the campaign after his victory at the Maybank Championship.
Zanotti began the day on the left of the 14th fairway having played his tee-shot on Saturday evening and made a birdie on the par five, a feat that would quickly be eclipsed by Hend.
The big-hitter had been six under on the par fives up to that point and he made an eagle to get back to level par for his round and extend his lead to three shots.
Hend dropped a shot on the 15th but his lead was soon back to three with Zanotti surrendering bogeys on the 16th and 17th to leave Fichardt - who had made three pars - alone in second at nine under.
That changed on the last with Zanotti bouncing back with a birdie and Fichardt dropping a shot.
Björk made three pars in his remaining three holes to join overnight clubhouse leaders Bjerregaard, Burmester and Fraser at eight under, with Fitzpatrick also in that group after bogeying the 16th upon the resumption.
Tyrrell Hatton and Duncan Stewart got finished on Saturday at seven under and they were joined by Stephen Gallacher who birdied the last, Richard Sterne who bogeyed the 16th, and Todd Sinnott who completed his round with four pars.
