Richard Mansell and Ivan Cantero tied at the top as fog disrupts first day in the mountains

Richard Mansell and Ivan Cantero share the lead following a weather-affected first day at the Omega European Masters after shooting opening-round 65s.

With a series of lengthy fog delays throughout the day limiting playing time at Crans-sur-Sierre Golf Club on Thursday, only eight groups completed 18 holes before play was suspended due to darkness just after 8pm local time.

Half the field did not start their rounds at all on day one and will get under way on Friday morning.

Mansell carded six birdies and one bogey while Spaniard Cantero made an eagle, four birdies and a bogey to join the Englishman on five under par.

Home favourite Ronan Kleu and South African Richard Sterne were in a tie for third one shot further back after 13 holes, alongside Italian Guido Migliozzi, who signed for a 66.

Two-time former champion Matt Fitzpatrick, who has three holes to complete on Friday, was among those on three under.

Mansell started from the tenth tee and made an opening bogey before bouncing back with birdies on the 12th, 15th and 17th to turn in 33.

He then finished with three birdies in his final four holes to get to five under.

Cantero, meanwhile, produced fireworks on the back nine as he holed a long-range birdie putt at the 13th before making an eagle on the 14th.
