Oakmont Country Club pro professional Bob Ford has detailed why Jason Day might have an advantage this week beyond talent alone.

Aside from being the No.1 golfer in the world, Ford was asked to offer the Queenslander his personal expertise in the weeks leading up to the US Open.

Day’s agent, Bud Martin, is a member of the exclusive Pennsylvania club, and engaged ford to take Day on a tour of the historic Major venue.

“Jason day’s agent, Buddy Martin, who’s a member here, I’ve taught him since he was 15, Buddy asked if I would walk around with Jason and spend most of the day with Col (Colin Swatton, Day’s caddie),” Ford said.

“And we talked a lot about what clubs to hit off tees and we spent a lot of time on the greens.”
