Emiliano Grillo made a hole-in-one at TPC Scottsdale's famed par-3 16th during second-round play at the Phoenix Open on Friday.

Drones fly over head. A fly cam whizzes by. There's a constant hum of noise from the fans, who erupt with every tee shot, and then depending on whether a golfer's ball ends up close to the hole or not, either loud cheers or raucous boos then ensue. Are you not entertained? Welcome to the Coliseum, the 16th hole at the WM Phoenix Open.
