Stadler and Scott lead Johnnie Walker

Paul Casey has put himself into the mix at the Johnnie Walker Classic at The Vines in Perth, shooting a four-under-par 68 to sit 11th, four strokes behind first-round leaders Kevin Stadler and Adam Scott on 64.

The Englishman birdied two of his first three holes of the day before recording another four birdies on the back nine in breezy conditions.
