What the USGA is saying is that the group in front of Sargent’s group pulled the pin and messed up the inner cup of the hole. So the ball hit the plastic and bounced out. I’m thinking if you are a caddie, and you are a caddie for a PGA tour pro, and you are caddying in a major tournament….you should know better.
Like you said GB, this is a major tournament, not your local muni. This could have had major implications. Lucky it didn’t.
