The roars could be heard across Royal Portrush.
Fans watching at the 13th hole were treated to something quite special as Englishman John Parry recorded the first hole-in-one of The 153rd Open.
The ace sparked huge celebrations around the packed green, with Parry enjoying a warm embrace with 1997 Champion Golfer Justin Leonard.
The 38-year-old finished his round with a four-under-par 67, and he sits at three-under overall.
Afterwards Parry said, "It was a great day. Obviously the sort of experience you get making a hole-in-one - the atmosphere was absolutely amazing."
He added, "I did hit a really good shot for once, so it was quite nice. It was quite a comfortable shot where I knew I had a big window to land the ball in.
"It was either going to pitch short, hit the downslope and feed down or - it went in a bit stronger than I thought it would from that distance for what club I hit. But I felt like it was going to be close."
Argentinian Emiliano Grillo managed a hole-in-one on the same hole - Feather Bed - when The Open took place at Royal Portrush six years ago.
