Tour. At the 2016 AT&T Pebble Beach National Pro-Am, Kang shot a course record 60 during the second round at the Monterrey Peninsula course. This took him into a share of the lead moving into the weekend: he finished the tournament tied for 17th. The following two weeks he finished in the top 10 in the Northern Trust Open and The Honda Classic. In April 2017, Kang took a three shot lead into the final round of the Shell Houston Open, the first time in his career he had held the 54-hole lead in a PGA Tour event. He finished second to Russell Henley. Two weeks later a good result in the RBC Heritage moved him into the top-100 of the world rankings for the first time, receiving an entry to the 2017 PGA Championship. He also finished tied for 5th in the Quicken Loans National, one of the Open Qualifying Series, to get an entry to the 2017 Open Championship. He tied for 44th place in both his 2017 major appearances. In July 2018, Kang was involved in a rules controversy at the Quicken Loans National tournament when he was accused of cheating by his playing partner Joel Dahmen. On the dogleg-left 566-yard par-5 10th hole, Kang's second shot landed in the hazard left of the green. After a short search, a spotter located Kang's ball some 5 to 8 yards into the hazard. There was no way Kang could play the ball. Instead, he began pointing to the spot at which he thought it had entered the hazard; nearly pin-high. Because the 10th hole is a dogleg left with a hazard all the way down the left side, Kang's ball would have needed to re-cross the hazard nearer the green in order to earn the drop he was requesting. The exact line his ball had taken en route to its final resting place thus came under careful scrutiny. There was a discussion with a rules official, Dahmen and Kang which reached an impasse as another group played through. After further discussion, Kang conceded that his ball more likely crossed the hazard 35 yards from the pin rather than his first suggestion. Kang dropped the ball at a point 37 yards from the hole, hit his approach to 17 feet, and holed the putt for a par. Later that night, Dahmen accused Kang of cheating on Twitter. The PGA
