Air cannon goes off in the middle of Zach Johnson’s back swing: video

Watch as Zach Johnson had the life scared out of him as an air cannon goes off as he was about to putt.

Jordan Spieth’s victory is the central talking point of the 2015 John Deere Classic yesterday, but another not so far behind is the fright than Zach Johnson received on the 16th green.

Johnson was over his birdie putt on the par-3 16th hole at TPC Deere Run when an air cannon was fired from a passing boat on the river. Johnson jumped and did extremely well to not make his stroke.

Johnson missed the birdie putt and would miss the playoff by one stroke.
