Royal Troon will have the longest hole in Open history when the Ayrshire links plays host to the 152nd championship in July.
The sixth hole will measure 623 yards - 22 more than it did when Troon staged the 2016 Open - when it hosts the battle for the Claret Jug from 18-21 July.
Two holes later, the players could then play the shortest hole in the championship's long history.
The iconic par-three eighth, the ‘Postage Stamp’, will measure 123 yards on the scorecard but organisers the Royal & Ancient (R&A) is considering reducing that to 99 yards for one round, weather permitting.
The R&A can use a forward tee and a front pin position to create a hole that would play fewer than 100 yards.
