Dustin Johnson has been thought of as one of the best young players in golf for years, but he hadn’t won a major heading into the 2016 U.S. Open. The previous year he three-putted 18 to allow Justin Spieth to win. In 2016 he was in striking distance on Sunday, but needed the leaders to falter a bit. They obliged but a potential rules infraction by Johnson at 5 hung over the round as the USGA refused to make a definitive ruling until after he finished. It ended up being irrelevant as Johnson pulled away but it certainly added some drama! Golf.com revisits the scene.
