Geoff Ogilvy may have a major to his name but concedes his golfing CV won&apost be complete unless he adds an Australian Open to the list of credits. The 2006 US Open champion will be one of the headline acts when the national championship gets underway at Royal Sydney from December 11 and he is already feeling the pressure to perform. “It&aposs the one I want to win,” Ogilvy said at Tuesday&aposs tournament launch on Sydney Harbour. “It definitely becomes a thing if you don&apost get it (an Australian Open win) early because every year you come back you get asked this question and it makes you think about it even more.” “You play well all year and the golf junkies see it but not many of the public see it so you want to show them you can actually play.” “It&aposs a bit like when you&aposre a kid and you play golf with your old man; you try too hard when you play with your dad.” “When we come back here we&aposre here so little we want to play well.” “That&aposs an added element that makes it difficult.” Ogilvy, who finished runner-up to John Senden in the 2006 Australian Open, heads into this year&aposs tournament a little underwhelmed by his form. The world No.18 took out the World Golf Championship in Florida in March ending Tiger Woods&apos run of five consecutive tournament wins – before his year took a dip. “It was a really rough start. I had my second child on January 7th so I took a true off-season,” Ogilvy reflected. “For two and a half months I didn&apost touch a golf club and I&aposve never done that.” “I missed my first three cuts and I was a little bit worried.” “I went to Florida and had a couple of top 10s and then won in Doral, which was a big story at the time.” “They were talking Tiger was going to win every tournament all year and no-one is going to beat him.” “I had a decent US Open but since then it hasn&apost been great.” “But I&aposve had a couple of good Australian Opens (at Royal Sydney) and I&aposve got pretty high hopes.” Ogilvy will face stiff competition, with Ryder Cup stalwart Darren Clarke in the field alongside 2005 US Open champion Michael Campbell, current US Amateur title holder Danny Lee, rising Japanese star Ryo Ishikawa and leading Australians Robert Allenby and Stuart Appleby.
