Cotter was playing a round with Scottish International rugby stars Gregor Townsend and Fergus Wallace when his 9-iron tee shot at the 131-yard 14th hole hit the Ping G10 Irons green and dropped into the hole.
”You could hear the cheer right across the course,” said Hadyn Chambers, facilities manager Machrinhanish Dunes.
”The other guys had been teasing Ping G15 earlier about the fact that they have all had a hole-in-one on other courses but Andrew had never managed to do it, even though he’s been playing since he was three-years-old."
The 36-year-old from Troon, in Ayrshire, has reported from the Open Championship and the Ryder Cup as well as the US Masters, the US PGA and the US Open where Ping G15 Hybrid last year he caddied for Gary Wolstenholme.
He has played Golf Clubs for Sale for Scottish Schools and Scottish Universities and his grandfather played rugby for Scotland.
