Ryder Cup captain Luke Donald hit out at the USGA after amateur Gordon Sargent saw a putt at the US Open amazingly bounce out of the hole.
Sargent’s par attempt from two feet on the 18th hole in Sunday’s final round was struck perfectly into the centre of the cup, but leapt back out on to the green.
The 20-year-old was still guaranteed to finish as the leading amateur following a 69 which left him four over par, but Donald was not impressed with the tournament organisers.
“This is unacceptable! Does the @USGA go fix this mid round? This should never happen,” Donald wrote on Twitter.
The USGA said the bizarre situation had been caused by the hole being damaged by a player or caddie in the previous group of Ryan Gerard and Mackenzie Hughes.
“A member of the group ahead inadvertently adjusted the hole liner when removing the flagstick,” the USGA said. “Unfortunately, we were not informed of any damage. It has since been adjusted back into place.”
