Collin Morikawa changed caddies once again, switching to a former college golf teammate for this week’s PGA Tour event.

Morikawa confirmed to Golfweek that KK Limbhasut will replace Joe Greiner on the bag in the Rocket Classic this week at the Detroit Golf Club.

Limbhasut, who was on the golf team at Cal with Morikawa, will be a one-week replacement.

Morikawa, who is ranked fifth in the world, made five cuts with Greiner as his caddie but was T-50 at the PGA Championship and T-23 effort at the Masters. He finished T-42 at the recently completed Travelers Championship in Cromwell, Conn.

Morikawa, 28, split with J.J. Jakovac on April 29.

Jakovac was Morikawa’s only caddie since he turned professional in 2019. Morikawa has six PGA Tour victories — including wins at the 2020 PGA Championship and the 2021 Open Championship. Morikawa last won at the Zozo Championship in October 2023.

Greiner parted ways with close friend Max Homa in early April before joining Morikawa.
