THE US PGA Championship is set to have welcome face on the scene in American Kelley Cahill.

But although she won't be hitting balls on the course, she will no doubt be in the limelight supporting her rising star boyfriend Jon Rahm.

Rahm was crowned world amateur number one for an incredible 60 straight weeks and tied 23 when playing at Oakmont in the U.S. Open 2016.

And Cahill also comes from a sporty background having competed in javelin for Arizona State.

She has also tried her hand at tennis and boxes on the side.

The couple have the potential to be the new faces of the sport and Cahill already has her fair share of Instagram admirers.

And it is no surprise as Cahill is not shy in flaunting her incredible figure in a series of bikini shots.

World number one Dustin Johnson and his partner Paulina Gretzky are currently the PGA super couple but they might not be for long.
