"It was a very freakish accident,'' Pope told ESPN on Saturday. "Kevin is devastated. He had trouble trying to finish the round. He was quite worried and felt so bad."
Tournament officials did not release the name of the spectator. Stadler, the son of 1982 Masters champion Craig Stadler, missed the cut in the tournament. He was not available for comment, ESPN reported.
Shaun Micheel, who was playing in the same group as Stadler on Friday, posted about the incident on his Facebook account, according to ESPN.
“I had my head down but the club head flew behind me and hit a spectator to my right," Micheel wrote. “It's been awhile since I've seen so much blood. We stayed with him for about 15 minutes before the EMTs arrived. ...
“[Stadler] was absolutely shattered and we did our best to keep his spirits up. This was not done on purpose and we were astounded at the way the club was directed, but it just shows you how dangerous it is to throw or break clubs. Each of us in the group learned something today.”
