Greg Chalmers will go after Australian golf's 'triple crown' after being confirmed as a starter in next month's Australian Masters, tournament organisers said on Wednesday. Chalmers, the winner of the Australian Open and Australian PGA Championship this month, is vying to become only the second player in history to win all three events in the one season. Robert Allenby did so in 2005. Chalmers, the West Australian left-hander, will have to overcome the challenge of world number one Luke Donald and Ian Poulter, both of England, Italy's Matteo Manassero and locals Geoff Ogilvy, John Senden, Allenby and defending champion Stuart Appleby. The Masters takes place at the Victoria Golf Club in Melbourne from December 15-18.
