Rudgeley ready to scale the heights for Swiss victory

Rudgeley, 23, said: "You need to prepare properly on this course. Get the right numbers and make sure the elevation is correct. With the mountains and the snow, I just kept looking around!

"Me and Harry [Ewing, my new caddie], it's our first tournament together. I've been looking for a caddie for a while and I think me and Harry get on really well. I'll see where it takes us. We hit some sensible shots and hit it pretty close all day, holed a few putts."

She shared the lead with Swede Caroline Hedwall, India's Vani Kapoor and Frenchwoman Anne-Charlotte Mora.

Another Australian, Whitney Hillier, was three shots back on a congested leaderboard, in a tie for 21st place.
