Dustin Johnson on Sunday entered the final round of the Byron Nelson Classic just two shots off the lead and in a five-way tie for second. He started his day with birdies on two of the first five holes before a total disaster on Hole 6.
Johnson carded an incredibly rare quadruple-bogey after losing his first tee shot out of bounds to the right. His second ball (third shot) went way left and into an area of extremely thick grass. Johnson took two shots to get out of there, another to get onto the green and then two-putted.
