Si Woo Kim's 60 helps him move 5 strokes clear at CJ Cup Byron Nelson

Si Woo Kim flirted with a sub-60 round and surged well clear of the rest of the CJ Cup Byron Nelson leaderboard in the second round on Friday in McKinney, Texas.

Kim's only bogey came on the 18th hole, when he overshot the green on his approach and left his chip short, missing an 18 1/2-foot par putt. He birdied 12 of the first 17 holes, finishing at 11-under-par 60 to sit at 18-under 124, five strokes clear of the rest of the field after tying the best round of his career with the 60 he shot in the second round of the 2016 Wyndham Championship.

The South Korea native is halfway to his first PGA Tour win since January of 2023 at the event approximately 30 miles outside of Dallas, where he now resides.

Defending Byron Nelson champion Scottie Scheffler (63) is one of four players tied for second at 13 under, alongside Wyndham Clark (63), Japan's Kensei Hirata (65) and South Korea's Sungjae Im (61).

Scheffler finished Friday's round a bogey-free 8 under. Five of those gained strokes came on Nos. 11-14, where he birdied the 11th, 13th and 14th and bombed a 46-foot putt for eagle at No. 12.

Round 1 leader Taylor Moore, who began the day at 9 under, followed it with a 2 under to land in a tie for 11th.

Brooks Koepka, who was 8 under in Thursday's round, also shot a 69 and is tied for 16th at 10 under.
