Collin Morikawa will have a new man on the bag next week when he tees it up at the 2025 Truist Championship in Philadelphia. Morikawa on Tuesday announced a split with long-time caddie JJ Jakovac with Colt Knost reporting that Morikawa's new caddie will be Joe Greiner.

Collin Morikawa has split with longtime caddie J.J. Jakovac and reportedly has hired Joe Greiner to replace him.

After Justin Thomas’s full-time caddie, Matt Minister, had to miss the Masters with a back injury, Greiner stepped in to caddie for Thomas. The part-time stint on the bag of Thomas was a short but successful one. The 31-year-old won in his second start with Greiner at the RBC Heritage in a thrilling playoff finish at Harbour Town.
