Keita Tosaki, who will be riding Stellenbosch for the first time in the G1 Yushun Himba (Japanese Oaks) said, "I am grateful to have been asked to work with Stellenbosch, but at the same time I feel a sense of responsibility." Also, "This is not the time to be thinking about the Derby," he said with enthusiasm.

The week-long prep workout, in which Tosaki rode, was 6F 83.6-36.9-11.1 on the woodchip course at Miho training center. "She looked comfortable, and her run was good," Tosaki added. "I will ride a leading horse in both the Oaks and the Derby. I want to spend my time feeling and enjoy that pressure and responsibility" he commented.
