"It's an awesome experience in front of a massive crowd, to see all the guys I've grown up idolising. I'm hungry to get a lot more.
"After playing one I'd like to play a few more. I feel I can compete with these guys. It was an awesome experience."
Fox snr - Next time he'll have the mental strength
Grant Fox said following his son in the legendary tournament at one of the game's most famous courses had been "strangely" easier than in Ryan's amateur days.
"I was a lot less nervous...(because) he hits the ball good and holes the putts now," he said.
Fox snr believed the performance at St Andrews would lay an important platform for the next stage of his son's career.
"It's not only the tips about golf. A couple of players have said 'you can play on this stage' and that's gold as well," said Grant Fox.
"Just to have those sort of experience, even the practice rounds. Hopefully there will be another time (when) just making the cut is not going to be enough.
"He was a bit flat on day three. Next time he'll have the mental strength to go again and that's what the top players do. They think about winning the damn thing.
"Even though he is 28, he's still a very young pro. He's going okay. We are very proud of him. He played incredibly well."
Ryan Fox returns to St Andrews for the Alfred Dunhill Links Championships in early October. That coincides with New Zealand's rugby World Cup pool game against Georgia in Cardiff and his father - an All Black selector - has been given the week off so he can follow his son again.
