Collin Morikawa Explains Why He Split From Caddie Joe Greiner originally appeared on Athlon Sports.
In October 2023, Collin Morikawa won the Zozo Championship, a tournament co-sanctioned by the PGA Tour and Japan Golf Tour. It marked Morikawa’s first win in 27 months.
That victory turned out to be more of a short respite than a true shift in fortune. In 2024, Morikawa had zero wins in 22 events with a pair of runner-up finishes and eight top 10s. It has been more of the same in 2025 across 13 events with no wins, two runner-up finishes and three top 10s.
Perhaps the inability to secure wins pushed Morikawa to seek a change because on Wednesday it was revealed the 28-year-old golfer is splitting with longtime caddie Joe Greiner, just two months after the pair came together.
Collin Morikawa on split with Joe Greiner:
“I think Joe is an amazing caddie… we were just a little bit on a different page. That doesn’t mean it’s right or wrong, but for me it just didn’t feel right. I have to explore other options.”

When asked about his decision, Morikawa explained what “didn’t feel right.”
“I think Joe is an amazing caddie,” Morikawa said. “We were just a little bit on a different page. That doesn’t mean it’s right or wrong, but for me it just didn’t feel right. I have to explore other options.”
Brian Kirschner of Inside Sports Net noted the two-time major winner has been tinkering with many parts of his game.
“Collin has spent the last three years tinkering with his caddy, putter, swing feels and glove on and off. Just truly incredible stuff, and I cannot think that hasn’t had an impact on his play,” said Kirschner.
Morikawa will rely on a former college teammate and current Korn Ferry Tour player, KK Limbhasut, to caddie for him at this week’s Rocket Classic in Detroit, Michigan. He has not yet found a long-term replacement.
At last week’s Travelers Championship, Morikawa finished T42. Since starting the season with two top 10s and four top 20s, he has dealt with a bad streak of underwhelming finishes, including a T54 at the RBC Heritage, a missed cut at the Zurich Classic of New Orleans and a T50 at the PGA Championship.
Morikawa remains one of the best golfers in the world and stands at 17th in the FedEx Cup rankings.
