We're almost halfway through the 2018 Open Championship at Carnoustie already, and things are certainly heating up at the top of the leaderboard.American Kevin Kisner finished at the head of the pack on day one, carding a score of five-under-par, and at the time of writing is currently two-under for the day through nine holes, leaving him still ahead on -7.Waiting for him to slip up are former Open champion Zach Johnson and England's Tommy Fleetwood, who are on six-under-par and five-under-par respectively.Big-hitters such as Rory McIlroy, Jon Rahm and Rickie Fowler will also be closely watching as their scores range from four-under to two-under, so all three are still in with a shout of winning the famous Claret Jug.Carnoustie is well-known for being a tough course, it's been nicknamed 'Car-nasty' by several golfers and pundits, and the fairways have been baked out by hot and dry weather, leading to long drives and hard bounces.The Eastern Scotland course has three tough final holes for players to contend with, but try telling that to Kiradech Aphibarnrat.The 28-year-old Thai player was 4-over-par through 16 holes in the first round, and was still on the fairway of 17 by the time his third shot came around on the par-four hole.And what happened next was simply stunning.

No-one knows if he was going for the birdie or an approach shot, but the ball only needed to bounce once before nestling in the hole to the delight of the crowd.

Aphibarnrat finished on three-over-par for the round, and has only just started his second round, but the projected cut at this moment in time is two-over-par, so he will need to card a one-under round or better to make the weekend play.

With big stars such as Henrik Stenson and Sergio Garcia set to exit early on though, it could give a chance for athletes like Aphibarnrat to make a name for themselves on one of golf's biggest stages.
