Si Woo Kim missed a 59 at the CJ Cup Byron Nelson after a final-hole bogey sealed his 60. The South Korean shot 11-under 60 with 12 birdies, including a curling 17-foot putt on the 17th hole. His only error came on the par-4 18th, where a short chip and misdirected putt cost him the chance for a historic sub-60. Kim now leads the tournament by five shots after two rounds.

The 17th hole’s transformation from a par-3 to a par-4 during the $25 million course overhaul proved costly. Designed by Lanny Wadkins, the new layout turned the hole into a strategic gauntlet, forcing Kim into a tricky chip-and-putt. His 19-foot chip landed short, and the follow-up putt lacked urgency, breaking right. This marked Kim’s first bogey of the day, derailing what could have been his 16th sub-60 round in PGA Tour history.

Kim’s 60 isn’t just a single number—it reflects the course’s evolving challenge. The par-4 18th, once a par-3, now demands precision, and Kim’s struggle there highlights the stakes. For a player chasing consistency, this near-miss underscores the fine line between dominance and frustration. With 12 birdies, he remains a threat, but the 16th sub-60 record remains just out of reach. This result keeps him in contention but adds pressure to maintain form on the final round.
