Brooks Koepka said he does not want to settle for second best, after his second top-five finish at a major.
Koepka matched the weekend output of top-three Jason Day, Jordan Spieth and Branden Grace - the quartet all going around in 133 strokes at Whistling Straits.
The former was left to rue his one-over 73 on Thursday that ultimately cost him a winning chance, but Koepka said his consistent outings at the 2015 showpieces meant he felt a major title was just around the corner.
He went 69-67-66 after his over-par start to finish at 13 under, carding the equal-lowest round on Sunday.
The Florida native was tied for: 33rd at the Masters, 18th at the U.S. Open, 10th at The Open and fifth on Sunday - and he was hoping the improvement continued in 2016.
"I think I'm ready to win one," Koepka said.
"I think that the more of them you play, the more comfortable you get.
"That's something I was telling my family not too long ago, it's just about being comfortable.
"You put yourself in an awkward situation, as long as you can learn from it, you're going to be better off the next time.
"I seem to learn from, whether it be good or bad, what I do on the golf course pretty well.
"[For] pretty much 12 months, I've just been trending upward, putting myself in good situations and that's good for you.
"I'm learning from it and I think that I'm ready to compete for majors, ready to win them, not ready just to compete."
Koepka, 25, said the success of fellow 20-somethings Jordan Spieth (22), Jason Day (27) and Rory McIlroy (26) at the majors was one source of motivation.
"I don't want to say it's a rivalry, but it fires you up a little bit," he added.
"Obviously, I'm happy for Jordan and what he's done this year. It's been incredible to watch. But it kind of lights you up inside. Get ready to get out there and kick his butt and I think that's something that is motivating the rest of us right now.
"But it's good to see them all play well. And especially in major championships, everybody seems to find their way to the top, which is great."
