World number one Tiger Woods will have his work cut out if he is to secure a third straight Open crown on Sunday, despite a third-round 69 at Carnoustie.
Woods can expect to be some way off the lead at the start of day four
The American was rarely at his best as he mixed four birdies with two bogeys to finish on one under par.
And the 31-year-old admitted it had been a "very frustrating day".
"Look, I've been here before and there are times when you just hang in there and grind it out. At least I have given myself a chance," he told BBC Sport.
"Of course it didn't go as I had hoped, but I still shot under par and we'll see how that looks at the end of the day.
"To win, I will have to play better than I have been but, like I say, I've given myself a shot at it at least.
"I remember Paul Lawrie came from 10 shots back to win in 1999, so it can certainly be done around here."
Woods enjoyed a fair amount of luck during his round, not least when a wayward approach on the sixth ricocheted off a female spectator and back into play.
Jennifer Wilson, 60, from Armagh, Northern Ireland needed two stitches in a head wound following the incident, but Woods went on to make par and keep his round on track.
And Jennifer's husband Cecil revealed that Woods made a heartfelt apology to the woman and gave her an autographed glove.
