Greg Chalmers and Aaron Baddeley are tied for sixth at the Humana Challenge heading to the weekend, with another five Australians also making the cut in California. Baddeley – a three-time PGA Tour winner – and Chalmers, searching for his first win on the illustrious US Tour, are level at 12-under par, some two shots behind joint leaders Roberto Castro and James Hahn, both of the United States. Tied for third is American trio Darron Stiles, Scott Stallings and Richard H. Lee – who all shot seven-under 65s to be one off the pace. Chalmers and Baddeley are among a group of nine completing the top-10, with Swede David Lingmerth the only other non-American among them. Lingmerth also shot the best round of those to finish in the top-10 on Friday, carding a sublime eight-under 64. The other Australians to make the cut were Geoff Ogilvy (tied 33rd), who is five shots from the leaders, Steven Bowditch, Matt Jones (both tied 43rd), Stuart Appleby and Scott Gardiner (both tied 60th). Unlucky Aussies were Alistair Presnell and John Senden, who finished tied for 78th and missed the cut by one stroke. Presnell had topped the leaderboard through his front nine on day one, but could only muster a two-under 70 on Friday. Adding to the recent big casualties of Rory McIlroy and Tiger Woods at the European Tour&aposs Abu Dhabi HSBC Golf Championship was that of Phil Mickelson, who bowed out in La Quinta by finishing tied for 91st on five-under overall, two shots off the cut.
