English teenager Kris Kim became the youngest player to appear on the PGA Tour since 2015 as compatriot Matt Wallace fell a shot short of the lead at the CJ Cup Byron Nelson.
Amateur Kim, 16, followed up his first-round 68 with a 67 to move to seven-under par in his PGA Tour debut.
“I’m happy,” said Kim, who had six birdies and two bogeys in the second round. “I can’t wait to do it again [on Saturday].
“I’ve enjoyed it so much the last few days and being here two more days makes it even sweeter.”
Kim is the youngest player to compete on the PGA Tour since 16-year-old Kyle Suppa at the 2015 Sony Open in Hawaii.
The day’s leader, Wallace, shot a five-under par 66, which included an eagle, four birdies and a bogey, to move to 13 under, with American Jake Knapp leading at 14 under.
American and world number 20 Jordan Spieth – the highest-ranked player in the field – missed the cut by two shots as he finished four under par after a second round 70.
