Louis Oosthuizen won't be nervous if he's leading heading into Sunday's final round of the US Open at Congressional.
The South African star is the only one of the last eight 54-hole leaders to prevail in a major.
Rory McIlroy's Augusta meltdown earlier this year showed just how tough it is to hang onto a lead over the final 18.
But it wasn't an issue for Oostuizen last year as he turned a four-shot advantage into an amazing seven-stroke victory in the Open at St Andrews.
"I was very confident the way I played," he said. "I was never scared on any shot and there was no particular hole that I felt scared of and I was driving it so well.
"At St Andrews everything is off the tee. If you can place it in a fairway all the time, missing all the bunkers, you've already won most of it.
"So that helped a lot. And it didn't feel like on the Sunday anyone really pushed me.
"I think the Friday night was probably the worst for me because I had 27 hours, I think, before my next tee time.
"But the way I finished on the Saturday, finishing two or three under the last five holes just gave me a bit of confidence going into the next day."
Asked what was the most important thing mentally he added: "The way I stayed in the present - I never for one minute thought of winning the tournament during the round."
Never for one full minute maybe, but certainly for a few seconds.
"It was so difficult the last six holes because with a seven-shot lead all of a sudden you're thinking of standing with the Claret Jug.
"You've got to get yourself out of that mind frame and think shot for shot.
"Only after my second shot on 17 did I feel like I'm not going to throw it away from here."
