(Officialsportsbetting.com) – Jon Rahm blamed a loud noise, reported as a slamming portable toilet door, for a poor chip shot at the final hole that cost him a chance of forcing extra holes in his final against Dustin Johnson at the WGC-Dell Match Play on Sunday. Rahm was just starting his backswing for the 80-foot shot at Austin Country Club in Texas when a sudden noise reverberated across the green. “That’s absolutely why I missed it,” Rahm told Golf Channel, referring to the noise, which NBC television said was a portable toilet door banging.
