South Korea's Kang Sung-hoon fired six birdies in a row on his way to a bogey-free 10-under par 61 Friday to grab a four stroke lead in the second round of the US PGA Byron Nelson tournament.
Kang, seeking his first US PGA title, stood on 16-under 126 after 36 holes at Trinity Forest Golf Club in Dallas, four strokes ahead of Matt Every and Tyler Duncan, who shot a 65 and 66 respectively.
Aided by cool early conditions, the Dallas resident opened with a birdie, his approach at the par-five first landing inches from the cup.
"It was perfect and awesome," Kang said. "I live in Dallas, about 30 minutes from the golf course, and I've never seen weather like this in May. I knew it was going to be cold and windy so I really tried to prepare for how far the ball was going to go this morning and it worked out great."
"I just tried to keep it in play," Kang said. "There are some par-fives so we can make some birdies and some short par-threes. I just tried to take advantage of those holes and miss it in the right spots. I missed it in the right spots where I needed to miss it and it worked out great."
"I hadn't thought about 59," he said. "I thought it was pretty far away until I finished."
