Si Woo Kim shot a 60 during the second round of the CJ Cup Byron Nelson on Friday [1].

The performance nearly resulted in one of the rarest achievements in professional golf. Had Kim converted a final putt, he would have recorded the 16th sub-60 round in PGA Tour history [3].

Playing at TPC Craig Ranch in Fort Worth, Texas, Kim maintained a dominant pace throughout the day [1]. His round included 12 birdies, split evenly with six on the front nine and six on the back nine [4]. The scoring surge was highlighted by a hole-in-one on the seventh hole and an eagle on the ninth hole [1].

Despite the momentum, the pursuit of a 59 ended on the 18th hole. Kim missed the putt that would have secured the historic score [2]. He settled for a bogey on the final hole, bringing his total for the round to 60 [3].

Kim's score stands as one of the lowest rounds ever recorded at the event. While he fell just short of the sub-60 mark, the 60 remains a significant feat of precision and consistency across the course [5].

A score of 60 is an elite achievement in professional golf, but the sub-60 barrier is a psychological and statistical threshold that few players ever cross. By missing the mark by a single stroke, Kim joins a very small group of players who have come within one putt of the historic 59, highlighting the thin margin between a great round and a legendary one.
