Paul Dunne, the young amateur from Ireland and Jordan Spieth, the World's number two, are set to fight it out for their own slice of history, after a weather-struck Open Championship.
Dunne is currently joint leader after 54 holes of play, alongside Louis Oosthuizen and Jason Day, at a score of 12-under-par. The Irishman got off to a flying start, making four birdies over the first nine holes, on his way to a score of 66.
Jordan Spieth matched Dunne's score of 66, having disregarded the frustrations of a second round, which saw the American post a score of 72. By the multi-major winners standards, that wasn't his best day in the office.

History in the making
Paul Dunne has elected to remain an amateur for the Open Championship and will there forgo any prize money he would have been eligible to collect. When its a few hundred pounds, its easy to stomach, but over £1million...Ouch! However I'm sure if he did decide to turn professional, he would make it back in sponsorship deals!
However if the young man from Ireland does lift the Claret Jug on Monday, he will be the first amateur player to win The Open, since the great Bobby Jones graced the game with his presence. Some may not have heard of Bobby Jones because most of us weren't born in 1930, the last time he lifted the trophy.

Jordan Spieth is also looking for another piece to add to his collection. The 21-year-old, who is one year junior to the Irishman, will be hoping one final good round will be enough to claim the first three majors in a calendar year.
This feat hasn't been achieved since Ben Hogan in 1953 and a win at St Andrews would put the third peace of the jigsaw in place, to complete the modern Grand Slam. However, we don't want to get too ahead of ourselves on that last one.
What about everyone else?
A surprise came in the way of another Irishman. Padraig Harrington set the course alight with a 67, putting him two shots behind the leaders. Only one score eclipsed Harrington's and that came from Marc Leishman with a score of 64.
Where Spieth and co used 'moving day' to their advantage, overnight leader Dustin Johnson slipped back down the leaderboard, with a disappointing three-over-par.
The US Open runner up finished with three bogeys which left him shooting the second worst score of the day.
