Si Woo Kim has clung to a two-shot lead in the CJ Cup Byron Nelson but has hometown favourite and defending champion Scottie Scheffler breathing down his neck.
The 30-year-old South Korean shot a 3-under 68 in the third round on Saturday to hold off a charge from Scheffler and 2023 US Open champion Wyndham Clark, who had matching 65s.
Sungjae Im, Kim's countryman, followed a second-round 61 with a 67 and was another two shots back with Stephan Jaeger and Tom Hoge. Jaeger's 64 was the low round of the day at the TPC Craig Ranch.
