The Hong Kong market is an important one for Australian breeders and a sire whose progeny excel in this jurisdiction adds an important string to his bow.

Yarraman Park’s I Am Invincible had seven winners from 10 runners in Hong Kong last season and sired a winning double at Happy Valley on Wednesday.

Prepared by Francis Lui, six year-old gelding Convincible won his last two runs at Happy Valley at the close of last season and resumed from a break in similar form.

Stakes-placed in Australia at three, he won over 1200 metres as favourite and has won five of 22 starts.

From the same stable, five year-old Fox Sunter broke his maiden with a neck win over 1200 metres after placing twice last season.

I Am Invincible colts are set to be in high demand at the yearling sales of 2018, not only for their sire potential, but also for their temperament and constitution that make them suitable for Hong Kong.

I am Invincible is fully booked at $110,000 this spring.
