JJ Spaun is doing his media duties now after signing for a 4-under 66.
He told Sky Sports he had no idea what to expect when he teed off this morning.
And it probably helped.
"My strategy was to take what the course gave me," he said.
"I scrambled well, putted well and that's the recipe you need to have a bogey-free round at the US Open.
"I had no idea what to expect teeing off this morning, as far as history here, never being here and this is only my second US Open.
"Maybe that freed me up, where I didn't have to worry about certain expectations.
"I'll take a bogey-free 66 at the US Open."
