During one of the breaks in the finals, I saw Kaci walk over to the ref and have a few works with her. Of course, I have no idea what they said. I do know that Kaci's break, which had normally been his strength, was not working, and he came with some dry breaks a few times.
After the celebration of Ko's win, Karl Boyes and Emily Frazer attempted a post-celebration interview with Ko, which was challenging due to his understanding of all English words. Ko said something about the rack as far as the break and was pointing to the table. I did not understand thoroughly what he meant, but he did indicate there was something troubling about him breaking and the rack/table/racking.
