"It wasn't an easy talk and I hope all the best for him," Morikawa added. "I hope guys are lining up for him because, look, if you look at his resume, if you look at what we've done just simply over the past six years it's incredible.

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.

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.
