Si Woo Kim lost all of the five-shot lead he built a day earlier while flirting with sub-60 history at the CJ Cup Byron Nelson.
The 30-year-old South Korean still managed to maintain an edge over a couple of major champions, including hometown favorite and defending champion Scottie Scheffler, heading into the final round.
Kim shot 3-under 68 on Saturday for a two-shot lead over top-ranked Scheffler and 2023 U.S. Open champion Wyndham Clark, who had matching 65s.
