World No.1 Jason Day’s late charge came up short as American Dustin Johnson buried his major championship demons in dramatic fashion, claiming the US Open amid controversy for rules officials.

The big-hitting world No.6, who had faced multiple close calls in majors thanks to rules infractions and late collapses, was approached on the 12th tee by officials informing him they were contemplating assessing a one-shot penalty for an incident on the fifth hole.
