Collin Morikawa knows it will be difficult to surpass the reception Rory McIlroy received at St Andrews after the world number two's fantastic start to the 150th Open Championship.
McIlroy will head into day two of the tournament just two shots behind leader Cameron Young after carding an excellent round of 66, in which he shot only one bogey.
The Northern Irishman won the Open in 2014, but missed out on the chance to defend his title at St Andrews a year later because of an ankle injury.
Yet he so far looks good to compete for winning his first major in eight years, and his fifth overall, with the 33-year-old receiving plenty of support from the crowd in Scotland.
When asked about the crowd reaction to McIlroy, Morikawa told reporters: "You hear your specks of Collin and specks of Xander, but it's hard to beat Rory."
McIlroy has been seen as something of a leader when it comes to speaking out against the LIV Golf Invitational Series, which has caused a divide across golf, with several elite players choosing to join the Saudi Arabia-backed breakaway competition.
Morikawa has also stood by the PGA Tour, though he is pleased to have McIlroy leading the charge.
He said: "I think you know all the guys that have spoke about the PGA Tour. We've all kind of said what we believe. Look, we all support each other.
"That's the biggest thing is like we're all here to play in the PGA Tour and do what we do."
Morikawa and McIlroy played together on the Sunday of the Masters, when the latter shot eight under to make a late charge only to come up short to world number one Scottie Scheffler.
McIlroy has enjoyed top-10 finishes in each of the previous three majors this season, and Morikawa believes he is competing against a player close to the top of their game.
Morikawa explained: "I mean, Augusta was near flawless. I'm trying to remember if he made even a bogey, I don't think he did.
"Today was a really solid round of golf. Didn't make any errors, hit it in the right spots.
"Overall, it was awesome. That's what I need the next three days if I want to get myself in the tournament."
Morikawa himself could only manage to shoot par for the day, meaning he has much work to do if he plans on retaining his title.
Disappointed with his performance, Morikawa remarked: "I just gave too many shots away on the greens, and it sucks. Sometimes you have those days.
"Today was just hit some good drives and hit a bad second shot, hit some good second shots, hit a bad putt. Never got any momentum going."
"This place is very special, for a lot of reasons. There's so much thinking to this golf course that it's great.
"I think that fits into what I like to do, but at the same time, you've got to execute. And if you don't execute, it's only a game plan."
