Collin Morikawa has broken up with caddie Joe Greiner after just five tournaments. He explained why at the Rocket on Wednesday.

Prior to Greiner, J.J. Jakovac served as Morikawa's caddie from 2019 until their split in April. Jakovac was on the bag for each of Morikawa's six PGA Tour wins, including The Open in 2021 and a PGA Championship in 2020.
