American Luke Guthrie takes a four-shot lead into the weekend at the BMW Masters in Shanghai, after an up-and-down 1-under par 71 took him to -8, while Paul Casey headlines a group of six players in second place on 4-under par. My prediction that John Daly would start brightly fade and then fade badly was largely right: two bogeys and a double bogey in the last five holes gave him a 2-over-par 74, to put him tied for 9th on 2-under par. But Rory McIlroy, Lee Westwood and Ian Poulter are among those lurking on 1-under-par and it should be a good weekend.
