Dominguez, who qualified for the Masters by winning the Inaugural 2015 Latin America Amateur Championship in Argentina, added that he is looking to enjoy his time at the Augusta National Golf Club as there is no pressure on him.
"Surprisingly, I'm really calm," he told the Associated Press. "But I know down the road here in one or two days, I'm going to get a little more excited. But I'm really looking forward to play good golf, because I've been preparing really well and really confident on what I've been doing."
While he has been honing his skills at Texas Tech, the Chilean has heard a lot of stories about the Masters and when he swent out onto the course on Monday, he was blown away by the warm reception he received.
"You hear a lot of things about how is the Masters going to be like, but nothing was even close," he said. "As soon as I stepped here this Monday morning, there were crowds everywhere. Everyone is excited and it's been lots of fun."
Dominguez started playing golf at the age of five, but never took the sport seriously until he was a teenager as golf is traditionally not a popular sport in Chile.
But, Dominguez did get the opportunity to speak to his compatriot, Enrique Orellana, who was given an invitation to the event 51 years ago.
When asked what advice Orellana had given him, the 22-year-old said: "He said, 'Try to enjoy it and have fun. Just try to learn the most out of it. You're going to be put in positions where you've never been before, and the most you learn out of it is the best you're going to be through it'."
