The only pro golfer to shoot 57 in a world ranking event is from Dublin - and he is giving himself every chance of Open glory this week.
David Carey was 18 when he turned professional seven years ago, deciding not to take the US college route but instead taking the plunge when he was successful in qualifying Alpine Tour - Europe's third tier.
"The only thing I can really fairly expect for myself is to go out there and do my best and try to commit to every shot," said Carey.
