GREENSBORO — Joohyung Kim walked off the 18th green, practically cackling to himself Friday at Sedgefield Country Club, the laughter from having left himself nearly 14 feet to save par on the hole and then promptly sinking the putt.

The Wyndham Championship has been an adventurous and amusing experience thus far for Kim, who used a 6-under-par 64 and another putting clinic during the second round to climb into a tie for the lead with Brandon Wu and Ryan Moore at 9 under for the tournament.
