Sho over 2000 metres at Kyoto Racecourse on 14 October. Plans to give her a warm-up race had been shelved after she sustained an injury to her right hind leg. Ridden by Yuichi Kitamura she was the second choice in the betting but failed to reproduce her best form and came home ninth of the seventeen runners. In the official ratings for Japanese three-year-olds Lucky Lilac was rated alongside Lily Noble and Mikki Charm as the second-best three-year-old filly of the year, thirteen pounds behind Almond Eye. 2019: four-year-old season On 24 February 2019 Lucky Lilac was matched against male opposition when she contested the Grade 2 Nakayama Kinen.
