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 Tour released a statement indicating that they regarded the issue as closed: "With no clear evidence to prove otherwise, it was determined by the official that Kang could proceed with his fourth shot as intended, following a penalty stroke and subsequent drop. The PGA Tour will have no additional comment on this matter."^[5] Kang finished third in the event, his best result of the season, and earned a place in the field for the 2018 Open Championship
