For the second time in three months, Collin Morikawa is switching up his caddie.
The American golfer confirmed to Golfweek Wednesday that he’s moving on from Joe Greiner after just five tournaments together.
Morikawa will have KK Limbhasut, his former college teammate at California, filling in for this week’s Rocket Classic at Detroit Golf Club.
Morikawa, 28, did not offer details on what went into the parting of ways, or who his long-term replacement on the bag will be.

Morikawa partnered with Greiner after parting with J.J. Jakovac, who had been the only caddie of his career, in April.
With Jakovac, Morikawa captured six titles on the PGA Tour and two majors: the 2020 PGA Championship and the 2021 Open Championship.
But Morikawa opted to replace Jakovac with Greiner, a veteran caddie who had been working for Max Homa since 2019.
Greiner made the decision to split with a struggling Homa just before the Masters.
“It was not my choice, so it sucked, but we always had a deal that we’re friends first and friendship mattered more than the work thing, and he was wise enough to do what he did,” Homa said at the time.

Greiner then went on to sub for the injured Matt Minister to caddie for Justin Thomas at the Masters and the RBC Heritage, which Thomas won, before joining forces with Morikawa.
Greiner first caddied for Morikawa at Wissahickon in Philadelphia, where Morikawa finished T-17.
The Los Angeles native then came T-50 at the PGA Championship, T-20 at the Memorial, T-23 at the U.S. Open and T-42 at the Travelers Championship.
Besides his switch on the bag, Morikawa was also seen discussing a potential putter change on the practice green in Detroit.
Morikawa currently is the fifth-ranked golfer in the world behind No. 1 Scottie Scheffler, Rory McIlroy, Xander Schauffele and Thomas.
However, Morikawa has not earned a win since the Zozo Championship in October 2023.
