 SYDNEY -- American sprint king Maurice Greene is getting right into the Aussie frame of mind -- no worries, mate -- as he chases Olympic gold.

 But the same cannot be said for teammate Inger Miller, who ruled herself out of the 100 meters on Wednesday with a hamstring injury.

 The world champion at 200 meters, Miller pulled out of the Sydney Olympics showcase event in order to give her injury more time to heal and hopefully allow her to race in the 200 and the 400 relay.

 "I have pulled out of the 100 because of a hamstring strain," Miller told the media today, two days before the start of track and field. "I didn't want to jeopardize the whole event. It's getting better by the day and it was possible I would have been OK by Friday but I cannot risk it."

 Miller's withdrawal ends her increasingly futile challenge of Marion Jones' dominance at 100 meters. She finished second to Jones at the U.S. Olympic trials and a European meet last month.

 Torri Edwards, who finished fourth in the U.S. trials, will take Miller's place in the blocks for the 100.

 There were also no "G'Days" from Greene as the world champion and world record holder in the 100 held his one and only meeting with the media before attempting to add Olympic gold to his collection of sprint honors.

 "Well, I'm going to win, that's what I'm going to do," Greene said matter-of-factly, as if it were already true. "I came here to get a gold medal in the 100 meters and that's what I'm going to get."

 With the exception of the three men who joined him on stage -- HSI teammates Ato Boldon of Trinidad and countrymen Jon Drummond and Curtis Johnson -- few would doubt Greene.

 In what has been an occasionally up-and-down campaign affected by niggling injuries, Greene has posted the four fastest times, including the year's best of 9.86 at Golden League meeting Berlin just before heading to Australia.

 Despite some inconsistency, Greene remains untroubled, bouncing around the stage like a kid on summer vacation.

 Told that British runners Dwain Chambers and Jason Gardner -- who have beaten him this season -- were boasting they could do it again, Greene questioned back, "You think so?

 "I guess anything can happen," chuckled the two-time world champion, still trying to supress a laugh.

 Greene also expressed a similar lack of concern regarding the Canadians -- reigning Olympic champion Donovan Bailey and world championship silver medalist Bruny Surin.

 In fact, Greene seems concerned only about enjoying his first Olympic experience to the max.

 He and Boldon, Drummond, Johnson and Miller are sharing a beach house in Coogee, where Greene says the biggest worry is who will make breakfast in the morning.

 The world's fastest man has been spotted driving around town in a Ferrari, catching a few rays at nearby Bondi Beach and taking in a movie at Darling Harbour.

 But the playful American has also been taking care of business.

 Reports have leaked out of the team's camp that the Kansas City Cannonball has broken the current world record of 9.79 several times during training sessions, further fueling expectation that the mark will fall sometime this weekend.

 "We'll have to wait and see, anything is possible," Greene said. "Do I think it's possible? Of course."
