Tianlang Guan, the 14-year-old amateur, was penalized a stroke for slow play at the par-4 17th hole during the second round. He was given a bogey on the hole - he took just four shots - and posted 75 for his second round.
Guan, Ben Crenshaw and Matteo Manassero were put on the clock on the 12th hole. At No. 17, Guan hit his tee shot in the middle of the fairway. Later, he was assessed a slow-play penalty on his second shot.
"I think our group was warned once that we were out of position," Crenshaw said. "This isn't going to end up pretty, I don't think. I'm sick.
"He's 14 years old. When you get the wind blowing out here, believe me you're going to change your mind. I'm sorry, I'm a player. It's not easy to get around this golf course."
