Greg Norman found life tough going in the first round of the Senior Open Championship as Bruce Vaughan and Eduardo Romero established a one-shot lead at Royal Troon.
Norman, 53, turned back the clock in sensational fashion in The Open at Birkdale last week, leading going into the final round before finishing third.
However, the Australian could only manage a four-over-par 75 - seven shots adrift of Vaughan and Romero's three-under total.
"Things just weren't going my way early on," said Norman.
"I just had to hang in there and guts it out the best I could. The ball just wasn't rolling my way. There's more than one round in a golf tournament."
Sandy Lyle, who pulled out midway through his first round at The Open because of the poor weather conditions, carded the same score as Norman.
England's Nick Job is among a group of four players one off the lead after a 69 while Bernhard Langer and Irishman Mark McNulty are both one-under along with defending champion Tom Watson.
The leading Australians are 1990 US PGA winner Wayne Grady and New South Welshman David Merriman at three-over.
