Martin Kaymer is confident his game is coming together at the right time as he aims to win a second US PGA Championship at Whistling Straits.
The German broke his Major Championship duck over the course in 2010 as he overcame Bubba Watson in a play-off in a run of form that eventually made him World Number One in 2011.
He has since claimed more Major glory in winning the 2014 US Open Championship but admits that his form in 2015 has been patchy.
The 30 year old has claimed three top tens on The European Tour this season but coming off the back of finishing in a tie for 45th at the World Golf Championships - Bridgestone Invitational, he is confident he can compete in the final Major of the year.
"The beginning of the season was fine," he said. "And then I said a lot already about the Masters, the preparation was all about the Masters. And I did so much, probably way too much practice, too much in the gym, too much focus on only one tournament and then didn't perform the way I wanted because I was going into the Masters a little bit tired already from that much practice, because I really wanted it really bad.
"It was just very, very frustrating. Very disappointing that I couldn't play the rounds that I wished for. It took me probably five, six weeks to get over it, really and to be okay with it and focus again on the upcoming tournaments.
"But the last few weeks I played really good golf. The score didn't really reflect it, but sooner or later it will."
Kaymer was just 25 years old when he won in 2010 and admits that winning a Major so early in his career relieved a lot of pressure.
"It's a feeling that you achieved something very special," he said. "It's a career goal and when you win one of those big tournaments, those Majors, early in your career, it takes a lot of pressure away as well.
"Obviously a lot of guys they fight for it for the last 10, 15 years, trying to get that Major, trying to get that Major, because you are apparently not a complete player if you don't, that's what everybody says.
"You've got so much pressure. I was very happy that I got this out of the way early and then you can really move forward and play a lot more relaxed."
Kaymer tees off with fellow former champions Tiger Woods and Keegan Bradley on Thursday and while he would love to win the famous Wanamaker Trophy again, he admits that lifting it is quite a tough proposition.
"Well at first it was super heavy. Everybody asks me to hold it up and I - you struggle at some stage to hold it up," he said.
"I'm not the Hulk or anyone, you know, but you don't really mind that because obviously you're so - I don't even know if you're happy in that moment because you're so in shock. I was really in shock. You could see my celebration was pretty much nothing because I didn't really realise what was happening.
"But it's a great trophy to have sitting in your living room, sitting in your kitchen when you get up in the morning and you have breakfast next to it."
