Martin Kaymer is hoping to draw on his experiences of the last five years as he aims to win a second US PGA Championship at Whistling Straits.
The German was already a five-time European Tour winner when he turned up in Wisconsin in 2010 and walked away with the Wanamaker Trophy after beating Bubba Watson in a play-off.
On Saturday, the 30-year-old fired a third round 65 after an opening pair of 70s to sit four shots behind leader Jason Day going into the final 18 holes, the same as he trailed Nick Watney by five years ago when he played alongside Day on the final afternoon.
And Kaymer admits that the knowledge he has gained since then in claiming a second Major at the US Open and winning three Ryder Cups has made him better prepared for pressure situations.
"I didn't make many mistakes back then. I hit a lot of fairways, I hit a lot of greens, it was just all about the putting," he said.
"Now, winning big tournaments in America, in Europe, the Ryder Cup, all those memories and all those experiences, how you feel as a player when you're in those critical situations under a lot of pressure, you learn a lot about yourself and you learn a lot about how you handle the pressure situations. Everybody handles them different.
"The funny thing is that you think, 'he's won two or three Majors here or there and he knows how to handle three or four holes', but every situation is so different.
"Because every time you play a different golf course, you play against someone different, and you can't really prepare for it.
"And that is what I didn't know five years ago. I thought those guys who won Majors before, they know, for them it's maybe just a daily business, on a little bit higher scale.
"But for me it was huge. And it is always huge, and I didn't realise it back then."
Despite his own stunning performance, Kaymer was overshadowed by playing partner Branden Grace who registered eight birdies in a flawless 64, and the 11-time European Tour winner was spurred on by the South African's form.
"It's a funny feeling when you play with someone that is playing as great as I played today, even better on a lot of the other holes," he said.
"And he made a lot of putts, too, great short game, didn't miss many fairways. So we really feed off each other, and it really pushes you."
