Collin Morikawa posted a fine opening round of five-under-par 67 at the Memorial Tournament on Thursday.
However, rather than revel in his fine play, Morikawa instead openly admitted that he made a big error a couple of months ago.
The Memorial Tournament at Muirfield Village is set up perfectly for the 28-year-old to succeed, what with the thick rough that punishes errant drives.
Morikawa recently admitted that his caddie Joe Greiner called him ‘crazy’ for the amount of different things he tries in practice.
That’s just the way the two-time major champion is, in his constant pursuit of perfection.

Morikawa actually seems to be getting on very well with his new caddie, and there are signs that he is close to rediscovering his best form.
His first round 67 at Muirfield Village on Thursday was certainly evidence of that.
But has he made things harder for himself than they needed to be?
Collin Morikawa admits to ‘shocker’ of a mistake in March after day one at Memorial
Following his fine round at Jack’s Place, the PGA Tour star addressed the media.
And Morikawa opened up on a big mistake that he made back in March just after the Arnold Palmer Invitational at Bay Hill.
He finished second that week, one shot adrift of eventual winner Russell Henley.
And he admitted that what he did in the aftermath of that tournament was a ‘shocker’ of a mistake.
Morikawa was asked after his round whether the swing thought he had in his mind on Thursday was the same one as he had last week.
He said, “No, no, no. It’s more of a swing thought that I had around Bay Hill. Shocker that I didn’t stick with it. Like I said yesterday, we’re crazy. We think one thing’s good, so then you just go away from that and try something new. But it’s just, honestly it’s just posture and making sure my posture’s really good from the ground up and allowing my body to just go from there and swing it.“

He then responded when asked if he looks at analytics much.
Morikawa said, “No, I would say some guys look at it a little bit more. I kind of know here and there.
“I mean they have the, I think it’s like the Sportsbox AI stuff that you can get all your numbers on your swing. The problem is, is my body keeps changing, as every year you get older your body changes, and the more work you put in or the less work you put in it’s just, it’s different than two years ago, five years ago, 10 years ago, right.“
Collin Morikawa’s 2024 vs 2025 PGA Tour stats
Morikawa is slowly making inroads towards rediscovering his very best form.
Here’s how his numbers this year stack up compared to 2024:
| PGA Tour statistical category | Morikawa’s 2024 rank | Morikawa’s 2025 rank |
| Strokes gained off the tee | 19th | 22nd |
| Strokes gained approach | 42nd | 7th |
| Strokes gained putting | 73rd | 54th |
| Strokes gained total | 5th | 6th |
| Scoring average | 15th | 11th |
Morikawa’s iron play is definitely back to where it used to be when he was at his best.
He has made slight improvements with his putting as well.
Morikawa just needs a week when his putter is really hot, and he will undoubtedly win again. Will that come at the Memorial Tournament? Only time will tell.
