Watch: Air cannon goes off as Z. Johnson putts
Silvis, Ill. – Zach Johnson stood over a 30-foot putt on the par-3 16th hole that would have tied him for the lead at 20 under.
He took the putter back, heard something that sounded like an explosion, and jumped in the air.
“I don’t know if it was like a pipe bomb or a backfire from a boat,” Johnson said. “I don’t have any idea, but I know it was loud, and I know I was about ready to hit my putt.”
According to David Feherty on the CBS television broadcast, the sound was from an air cannon on a pontoon boat heading down the Rock River, which runs adjacent to the 16th hole.
