Yarraman Park’s flagship sire I Am Invincible posted his 15th two year-old winner of the season at Kembla on Tuesday with a debut victory for the Joe Pride trained gelding Fifteen Rounds.

He travelled last in the field of six for Corey Brown and swept home at the finish to beat the older horses and win the open 1000 metre maiden by a neck.

A $200,000 Inglis Easter purchase for Pride Racing from the Yarraman Park draft, Fifteen Rounds is the third winner for stakes-winning import Sugar Bay (Can).

Fifteen Rounds was bred by Ron and Rod Dufficy, who retain a share in his ownership, and his win will be well received given the mare has a weanling colt also by I Am Invincible.

With 15 two year-old winners on the board, I Am Invincible moves to second behind Spirit of Boom on the leading Australian two year-old sires by winners list.

He stands this spring at a fee of $192,500.
