THE CJ CUP Byron Nelson: Korea's S.H. Kim boosted his quest for a maiden PGA TOUR victory as he surged into joint ninth place at THE CJ CUP Byron Nelson on Friday while Japan’s Taiga Semikawa also stayed within striking reach of 36-hole leader Jake Knapp.

The 25-year-old Kim delivered a bogey-free 7-under 64 at TPC Craig Ranch to lie four strokes off the pace on 10-under, which was matched by Semikawa, who returned a 68 in the US$ 9.5 million PGA TOUR showpiece.

Jake Knapp, who just over two years worked in security at a restaurant in his hometown, took the halfway lead. A first-time TOUR winner earlier this year, Knapp went into this weekend leading THE CJ CUP Byron Nelson after a second consecutive 7-under 64 on Friday.
