Kiwi bred Gringotts continued his coming-of-age campaign with a powerhouse front-running performance under 60kg to win Saturday’s Group III A$1 million The Illawarra Mercury Gong (1600m) at Kembla Grange.

The Karaka Millions 2YO (1200m) has been the goal for Sierra Leone from the moment she was purchased at the Yearling Sales, and she took an important step towards the $1 million feature with a game second in Saturday’s Listed Counties Challenge Stakes (1100m).
