But it all took an unfortunate turn when, while celebrating the ace, Finau fell and seemed to roll his left ankle hard in the process.
With his ankle visibly damaged, he appeared to lean down and simply push it back into place before limping back to the tee.
Finau, who was playing with his mother and children, aced his shot and chose to run up to the green in celebration. Thanks for thoughts of concerns, messages and prayers from all. However he tweeted on Wednesday night, saying: "Crazy day".
Tom Watson won the contest, shooting 6-under PAR - one shot better than Tommy Fleetwood and Thomas Pieters.
Thankfully, the injury, which was later confirmed as a dislocated ankle after an MRI, doesn't seem as if it will knock Finau from trying to compete on Thursday and Friday.
Of Tongan and American Samoan descent, Finau is the first person of such ancestry to play on the PGA Tour. Finau ranks 11th in strokes gained: tee-to-green, 17th in strokes gained: approach-the-green and 22nd in strokes gained: total.
Finau's upcoming Masters tournament must have flashed before his eyes after the tumble, but here's hoping he will be fine to continue in the coming days. It's the only tournament I watch on TV, and I watch it all four days.
Tony Finau is a rising star in golf, and he's playing his first Masters this week.
