The teenage New Zealand golf star Lydia Ko has the benefit of one of the game's most experienced caddies for this week's US Open championship at Pinehurst, the famous course which hosted last week's men's US Open.
Mike "Fluff" Cowan, Jim Furyk's regular caddie on the PGA Tour, is giving Ko the benefit of his course knowledge as she plays alongside the defending champion American Christie Kerr, and the Norwegian star Suzann Pettersen for the opening two rounds.
It's 17-year-old Ko's first US Open as a professional.
