It is just the ninth hole-in-one on Pete and Alice Dye's penultimate hole on the TPC Sawgrass Stadium Course in the PGA Tour event's history, and the first since Sergio Garcia's ace in 2017. He hit it perfectly but, with the pin at the front of the green, he was anxious the ball might spin into the water.
But the biggest roar came for Moore when he struck a 121-yard sandwedge dead on, his ball striking the pin and shooting straight into the cup.
"That ace on 17 was pretty unbelievable", said Moore. Fred Couples, Hal Sutton, Steve Elkington and Davis Love III obviously aren't here this week but there is one competitor in the field this week with a chance to join The Golden Bear and I bet you know who it is. As the week progresses, I'll go at more flags and commit to more swings.
Thousands of golfers, from major winners to weekend duffers who shell out close to $500 for a round on the public course, have watched their balls plunk into the murky waters guarding the infamous green.
Jay Monahan, PGA Tour commissioner has ruled out his organisation creating its own rules saying he was happy to leave that task to golf 's two global governing bodies.
It is one of the most famous holes in golf because of an "island green" - actually a peninsula - that is surrounded by unforgiving water.
Ryan Moore just nailed one of the most spectacular shots of the year.
"It is like having a 3 o'clock appointment for a root canal", said Mark Calcavecchia in 2009.More news: Captain Marvel lands at California Adventure Park ahead of Marvel expansion

"With a huge volume of (visitors) playing the course every day they have to keep the greens and fairways longer". Tiger Woods, the only man to win the tournament in both May and March, also returns to TPC Sawgrass.
"I had to put the hammer down on 16 and 17 and 18", recalled Woods on Tuesday about his run for the title past year.
"I'm hoping for soft greens in the morning so I can make a push and watch the guys battle in the afternoon (breezes) like we did today".
He also has some good memories from the hole, however.
"I felt like a few times I played well around here, it's just I couldn't ever get anything going".
In the video comedian Paul Gutkowski was given the task of informing groups that they were not going to be able to play the 17th hole.
"The way I've been hitting the ball, I find the 17th a lot easier", Baddeley said.
