Collin Morikawa splits with caddie Joe Greiner after only 5 tournaments

After a five-year-plus run with his first caddie as a professional golfer, Collin Morikawa only made it five tournaments with his second.

The two-time major champ is making a second switch on his bag of 2025 at this week’s Rocket Classic, splitting with Joe Greiner. Golfweek first reported the news on Wednesday from Detroit Golf Club.

Morikawa linked up with Greiner in April. Greiner was coming off a successful two-tournament fill-in stint with Justin Thomas, helping him win the RBC Heritage. Previously, Greiner was the longtime looper of Max Homa.

Greiner had been a replacement for JJ Jakovac, who had looped for Morikawa since he turned pro in 2019. Jakovac was on the bag for both of Morikawa’s major titles at the 2020 PGA Championship and 2021 Open Championship.

“I think people, they’re going to be surprised but the way I put it is just because two people are great at what they do doesn’t mean they’re going to be great together,” Morikawa told reporters after Wednesday’s pro-am. “I think Joe is an amazing caddie, but I think just the way we kind of saw things or just day to day how we kind of went about it, 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.”

Collin Morikawa will have his old college teammate from Cal, KK Limbhasut—who’s currently playing on the Korn Ferry Tour—caddying for him at this week’s Rocket Classic, Golfweek reports.

“I’m at a point where I need to look at some new options,” Morikawa explained. “I went into this knowing it was going to be a good trial run, something fun to try out. But the truth is, you don’t know how things will work out until you’re in it. We spend so much time with our caddies—honestly, more than anyone else, sometimes even more than our spouses. It really is a serious partnership.”

Despite being ranked No. 5 in the world, Morikawa hasn’t won on the PGA Tour since his 2023 victory at the Zozo Championship—his only win since lifting the Open Championship trophy almost four years ago.

With JJ Greiner on the bag for his last five events, Morikawa had mixed results: a tie for 17th at the Truist Championship, T-50 at the PGA Championship, T-20 at the Memorial, T-23 at the U.S. Open, and T-42 at the Travelers.

“No hard feelings at all toward JJ or Joe,” Morikawa added. “But for now, I just needed someone to step in. KK’s a great friend from our college days at Berkeley, and even though he’s still grinding it out on the Korn Ferry Tour, he agreed to help me out this week. I really appreciate it, and we’re just going to have some fun out there.”
