South Korean golfer Si Woo Kim made history at the British Open by hitting the first hole-in-one on the 238-yard par-3 17th hole at Royal Troon, the longest in the tournament's history. The shot marked the first ace on the hole in any British Open, prompting huge celebrations and making it Kim's most memorable hole-in-one of his career. Despite this historic achievement, Kim remains 5-over for the tournament and is not in contention for the win. Kim, ranked 48th in the world, has had a challenging season with only one top-10 finish. This ace, however, stands out as a significant highlight in his career.
