Jason Day might have some extra support at Oakmont at this week's US Open after playing a practice round bedecked a pair of red, white and blue American flag shorts.
To complete the patriotic all-American look, the flamboyant Queenslander sported a quarter-zip jacket that featured a blue and white star-lined collar.
Day is one of six Australians in the event, with their challenge to be led off by Adam Scott when the 125th US Open starts just outside Pittsburgh on Thursday.
