Yang’s manager, Ryan, alerted the golfer’s followers on Twitter that Yang was nursing a sore shoulder and was “considering retiring the tournament.” Shortly thereafter, Yang called it quits after just four holes. He was 1-over-par at the time. Later, Yang himself wrote the following on Twitter: “Its my first WD, and it doesn’t feel right. I just couldn’t bear with the pain. Never want to do this ever again. Sorry to those who lost $.” An Associated Press report cites that Yang has a neck injury. We’ll stick with the shoulder until Yang confirms otherwise.
