Scottie Scheffler admits life has changed for him since winning the Masters, as he prepares for the spotlight at this week's US PGA Championship.

Scheffler has tried to remain on an even keel after his Masters win last month and a rapid rise to the top of golf's world rankings, but cumulative changes to life on the PGA Tour have not gone unnoticed.

The 25-year-old's win at Augusta National made him only the second player in history after Arnold Palmer in 1960 to win four tournaments including the year's first major in such a short space of time at the beginning of the season.

Heading into this weekend at Southern Hills, Scheffler noted that while he is trying to block out external factors, his roaring start to the year has provided a growth in belief.

"I would say when I show up to tournaments, it's a little bit different," he said. "There's more people kind of hollering at me when I'm playing a practice round wanting to get signatures or whatever it is.

"At home, I've been recognised a few more times than I did in the past. But I kind of stay in my own little bubble, and for me not much has changed when I'm at home. Not much has changed the way I practise. When I show up to tournaments, I don't feel any different.

"I will say, after my first win in Phoenix when I was in contention, and Bay Hill, I definitely took some confidence from Phoenix. I think I made four bogeys the first 11 holes and still won the tournament, and I think in the past, I believed I had to play perfect golf on Sunday in order to win.

"And I would say that's probably really only biggest change was that Sunday at Bay Hill, and like I said, I made some mistakes then, too, and I was able to kind of pull out the tournament. Golf is really chancy. It's not consistent like other sports. We play outside, there's bad waves, bad bounces, all kinds of stuff that can happen. For me just trying to keep my head down and play good golf."

Aside from team play at the Zurich Classic of New Orleans, Scheffler's return to the golf course from his Masters win came at the AT&T Byron Nelson this past weekend, where he tied for 15th.

The world number one believes his ranking or burgeoning status does not substantially change anything, in relation to the rest of the field this week.

"Tiger's here so nobody really remembers that I'm here, so it's all good," Scheffler said, joking. "Like I said, I don't feel any different. I don't get any extra shots this week. It's nice to have the ranking, but at the end of the day when I show up at a tournament, I don't have any advantages over the field other than we all start even par.

"For me, it's a tremendous honour, but at the end of the day when I show up to a tournament, I'm starting at even."
