The golfer failed with the driver on the tee of hole 11, and sent his ball right where a spectator was calmly following the game next to a tree. The ball hit the spectator's nose directly, causing him to fall to the ground.
The individual's mistake was standing in front of the tree, rather than behind it, which made him an easy target for any wayward ball. The spectator was able to recover from the hit, although he ended up with a broken nose.
