Jeremy Kavanagh was high on the leaderboard with golf's top names
Hertfordshire's Jeremy Kavanagh was high on the leaderboard at three under at the turn before falling back on the back nine.
The one-time building labourer, who finished four over on 74, had practised with Tom Watson and Greg Norman.
He said: "I've met and played with some great names. A bit of it was bound to rub off.
"I'm not disappointed. It's just been a great experience. A bit up and down, just like my whole career so far."
After reaching the turn in 32 shots, still on three under, after his birdies at the first, the short sixth and the seventh, Kavanagh buckled on the back nine to come back in 42.
Bogey fives at 10, 12 and 14 were interspersed with one more birdie at the 13th. But he then suffered painful back-to back double bogeys at 16 and 17 before losing another shot at the 18th.
He added: "I've had an amazing day. In fact I've had an amazing week.
"I played one practice round with Tom Watson and Greg Norman, then the following day I went out with Steve Stricker, Davis Love III and the new US Open champion Lucas Glover."
Fellow qualifier Tom Haylock, also from Hertfordshire, also shot a 74. And he too had red numbers against his name after starting with an encouraging birdie at the difficult 489-yard third.
"I hit driver, then pulled my six iron left of the green and holed my pitch from about 30 yards," he said.
He then bogeyed the fifth to go back to level par at the turn. But bogeys at 11 and 12, followed by two more at 17 and 18, saw him card a four-over 74.
"I'm a bit disappointed, to be honest," he said. "I've just got to take out the mistakes and see what happens tomorrow."
Haylock at least outscored Hertfordshire's most famous golfing son, Sir Nick Faldo, who shot an eight-over 78, in the three-time champion's first Open since his knighthood.
But another Hertfordshire golfer, Hemel Hempstead-born Luke Donald, is far from out of it after a first day one-over 71.
"I would have liked to see some red numbers," he said. "But, while one over is not great, it's certainly not terrible."
