THE STORY
During the final round of the 2016 U.S. Open at Oakmont Country Club, Dustin Johnson's ball moved slightly on the fifth green as he prepared to putt. Initially, no penalty was assessed. However, after completing his round, the USGA reviewed the incident and imposed a one-stroke penalty, reducing his score to four under par. Despite the penalty, Johnson secured his first major championship, winning by three strokes.
