Dustin Johnson's win at the US Open will go down as one of the best mental performances at a major in recent memory.

On the 12th tee of his final round, Johnson was told he may have been given a one-shot penalty at the end of his round for an alleged infringement on the fifth green. For the rest of the tournament, Johnson and his nearest rivals (including Shane Lowry) all played on without knowing what their exact position was.

Johnson called a rules offical on the fifth, after notifying him his ball moved backwards as he prepared to take a putt. Playing partner Lee Westwood backed Johnson up immediately and stated that the ball moved without any influence from the American.

Despite both players leaving the fifth green, assuming the incident was over, USGA officials returned to Johnson after he parred the 11th.

After leaving the course on -5 with a remarkable birdie on 18, Johnson was eventually penalised a shot for what happened on the fifth. His four-shot victory turned into a three-shot one.

Players took to Twitter to speak about the incident and the treatment of Johnson. They were all in unison about the unfair pressure put on the 31-year-old.
