USGA has issued a statement. “regrets the distraction”
Not only was it unfair to Dustin, but the players behind him in the standings. They didn’t know how far behind they were! What an embarrassing disaster.
Interesting article about the support Dustin Johnson had coming down the stretch. He also had lots of support from fellow players and fans on Twitter, but wouldn’t have known about that until after he finished the round. http://www.cbssports.com/golf/news/how-lee-westwood-helped-dustin-johnson-win-the-2016-u-s-open/ Of course, it was Dustin that fought through and won, but he seems very thankful for the support.
