SCOTTSDALE, Ariz. — The Thunderbirds almost lost Mike Leonard.

It was the "Racing of the Bros" at the third round of the WM Phoenix Open, as fans rushed to get a spot at the iconic 16th hole.

Emiliano Grillo’s hole-in-one in the second round Friday at the Waste Management Open gave the fans at the rowdiest hole in golf a reason to go wild.

Fun? It's lining up at obscene hours to risk personal injury and race roughly a mile and a half to the coveted 16th-hole grandstand seats.
