A US Open at famed Winged Foot holds few fears for Collin Morikawa and golf's newest major champion is hungry for more major championship glory.

Playing in just his second major and 28th tournament since turning professional in June last year, Morikawa won the US PGA Championship last month after a brilliant final round of 64 at Harding Park in San Francisco.

The 23-year-old missed the cut in his next start but finished 20th at the tough Olympia Fields in the BMW Championship and is relishing another testing examination at Winged Foot this week.

"You're going to hear that all week. Guys that are going to play well are going to take their medicine and scramble really well. That's just the way this course is going to play out."

Asked if being a major champion would alter his approach going forward, Morikawa added: "I don't think I approach it any different. I think I do a really good job Monday through Wednesday of figuring out a course, figuring out what I need to do, so I'm doing the same thing.

"But I think walking here as a major champion, you have a sense of knowing how to get things done. Yes, I've only done it once, but I've done it. You just want more. You get that little taste of what it's like, and you know why guys mark in their calendars the major championships for the year.

"I'm not waking up every day realising, yeah, I'm a major champion. I'm realising we're at the US Open, let's go win another tournament."
