Si Woo Kim keeps two-shot lead over Scottie Scheffler at CJ Cup Byron Nelson

Si Woo Kim turned a round that had brushed against PGA Tour history into a survival test, and he still emerged Saturday with a two-shot lead. After chasing a sub-60 on Friday and watching a five-shot advantage disappear, Kim carded a 3-under 68 at TPC Craig Ranch in McKinney, Texas, to reach 18-under 198 and stay in front of Scottie Scheffler and Wyndham Clark at the CJ Cup Byron Nelson.

The volatility was the story. Kim’s second-round 60, built on 12 birdies, had put him at 18-under 124 and sparked real talk about becoming the 16th player in PGA Tour history to break 60. A par on the 18th would have done it, but a bogey there left him one shot away from that milestone and set up a weekend in which the margin looked much safer than it played. By Saturday, it had shrunk to a two-shot lead over two of the field’s most dangerous pursuers.

Scheffler and Clark matched 65s to get to 16 under, keeping the pressure squarely on Kim entering the final round. Scheffler was not just another chaser. The hometown favorite and defending champion won the 2025 Byron Nelson by eight shots and tied the PGA Tour’s 72-hole scoring record at 31-under 253, making him the obvious threat if Kim’s lead wobbled. Clark, a three-time tour winner and the 2023 U.S. Open champion, also carried the kind of firepower that can erase a margin quickly on a course still yielding birdies in bunches.

That is what made the setup so unforgiving. TPC Craig Ranch, about 30 miles north of Dallas, has been renovated for precision, but it has still played as a scoring course in soft conditions and light wind. The new greens, which reopened to members on December 12, 2025 after a $25 million renovation led by Lanny Wadkins, have added slope and undulation. The 18th hole is now a par 4 for the first time in the event’s six editions at the course, another sign that low scoring has remained available without ever feeling safe.

The tournament also carries a heavier backdrop than a simple leaderboard chase. Hosted by the Salesmanship Club of Dallas, the event has raised more than $195 million for Momentous Institute since 1968. Sunday’s final pairing also had a personal edge: Scheffler and Kim are friends and nearby Royal Oaks Country Club members, turning a birdie hunt into a direct pressure test of whether Kim could finish against the sport’s biggest names rather than merely flirt with a historic number.
