Golfer furious with PGA officials after bizarre pin-position blunder

"It sucks. That could be the difference between me playing tomorrow or not."

American Colt Knost was furious with tournament officials after his bid for a first major title was hampered in bizarre circumstances in the US PGA Championship.

Knost was in the first group out at 7am local time and began the day just four shots off the lead held after carding an opening 69 at Baltusrol.
